Well here are some young players who promises to be top players in a future or they already are in the top.
ATTENTION: The list doesn't respect any order. Please don't blame to me if you don't like something. And I'm sorry for my bad spelling, English is my 5th language. Soon I will make another part of young players who promises.

Name: Neymar Da Silva
Nationality: Brazilian

From childhood, Neymar has attracted interest from professional football clubs in Europe and Brazil. He was hired by the Santos in 2003 where he wanted to follow in the footsteps of his idol Robinho . Its characteristics are similar to this (for example, is cleared down the left).

In his first full season as a starter, he won the National Union of Professional Footballers (UNFP) Young Player of the Year award becoming the first non-French player to win the award.

Name: Romelu Lukaku
Nationality: Belgian 

Age: 18 years 
Club: FC Chelsea
Position: Forward
Romelu Lukaku impressed for Anderlecht at a very young age and it was no surprise when Chelsea paid a relatively high transfer fee to sign the striker. He boasts an immense physique and looks like he can handle the physicality of the Premiership. Lukaku still has to work on his technique and on some other aspects but it is hard not to compare him with Didier Drogba, when the latter was young. Lukaku has the attributes needed to be a superb striker in the future but needs the right guidance and will hopefully be a regular for the Blues in the near future.

Nationality: Brazilian 

Age: 19 years 
Club: Inter Milan 
Position: Attacking midfielder

Name Erik Lamela
Nationality: Argentina 

Age: 19 years 
Club: AS Roma 
Position:  Attacking midfielder

Erik Lamela is a skilled playmaker who can also act on both sides, preferably the left. Lefty leg, we could say that is one of those players unable to use his bad leg, but it has that quality that makes the balance left everything else. Among his most outstanding qualities are technical quality, a huge ability to overwhelm and impudence worthy of a top player. Let's go to the first, the technical quality because you do not need him much time to realize that a single action you may decide to move, either a pass or a dribble, but the quality that holds his boots have been made delight of the fans of Argentina in recent games. Ability to overwhelm an attacker because it is very correct, which has a left foot capable of creating mischief most unexpected rival for the defender, who always seems to rile. Fast, flexible and highly skilled, Lamela is always shown as a very difficult player to stop, who likes to combine with peers and come into play as possible.

Club: Barcelona 
Position: Midfielder

Thiago Alcântara known simply as Thiago, is a Spanish football player who currently plays as a central midfielder for FC Barcelona.

Sergio Araujo is one of the players who could be a top quality striker in the future. He looks to be technically excellent and has the pace and skills to beat defenders. Argentina have been fortunate to have many top quality strikers in the recent past like Sergio Aguero and Gonzalo Higuain and Araujo could be one of the future stars if he continues to progress. If he performs consistently and shows the right attitude, it will not be long before some of Europe's big clubs are interested in acquiring the services of the striker.

Name:Oriol Romeu
Nationality: Spanish 

Age: 20 years 
Club: FC Barcelona 
Position: Defensive midfielder
He is one of the best if not the best defensive midfielder around the world of his age. He plays like an experienced player. He is a natural footballer and knows his way around the field. Oriol is very comfortable on the ball, something not many young players have. Protects the back four well. Hardly does any mistakes too. He isn't OUTSTANDING though. A very above average player. 

Name: Rafa Alcantara
Nationality: Spanish/Brazillian 

Age: 18 years 
Club: FC Barcelona 
Position: Attacking Midfielder

Rafa Alcantara is one of the best young midfielders to emerge recently from Barcelona and his brother Thiago is another player who looks promising. Rafa Alcantara is also an attacking midfielder which is why it will be difficult for him to find enough playing time but with his talent, it will not be a surprise if Guardiola does give him the opportunity to impress at the Nou Camp. 

Name: Gerard Deulofeu
Nationality: Spanish

Club: FC Barcelona 
Position: Winger

Barcelona have produced some of the best talents in the recent past and youngster Gerard Deulofeu could be another player to shine for the Catalan club in the future. It is clear that he is a player with a lot of talent but needs to be further developed to be a better player. Pep Guardiola is a manager who has helped several players to mature in the side and Deulofeu could be another player who could be integrated into the main team. He will face severe competition for his place at Barcelona. He has the quality to make an impact for Barcelona but the question is whether he has the patience and the right attitude to excel at the club.

Nationality: Croatia

Age: 18 years 
Club: Dinamo Zagreb
Position: Attacking Midfielder
There have been some excellent Croatian players in the past decade such as the likes of Niko Kranjcar and Luka Modric and youngster Mateo Kovacic has the quality to be a top player in the future.

Name: Josh McEachran
Nationality: England

Age: 18 years 
Club: Chelsea
Position: Midfielder

Josh McEachran is one of the finest talents to emerge from the Chelsea academy in the recent past and is technically excellent on the ball. He still has some way to go before establishing himself as a regular in the Blues side but he certainly has the quality to make an impact in the future. In the short term, a loan move to a Premiership club would give him more experience and could fast-track him into the Chelsea side. A loan move to Bolton worked for Jack Wilshere and Daniel Sturridge and a loan move could similarly benefit the young midfielder.

Name: Souleymane Coulibaly
Nationality: Ivory Coast

Age: 17 years 
Club: Tottenham
Position: Striker

Souleymane Coulibaly has shown that he has the quality to be a top quality striker in the future and was in sensational goalscoring form in the U-17 World Cup for Ivory Coast.

There are a number of talented African football players in the world and Nigerian winger is one  of the most talented players to emerge from Nigeria. Ahmed Musa is a very talented winger who threatens the oppositions with his direct play and with a lot of pace and trickery, he has the ability to influence games. He has been an important player for Dutch club VVV Venlo and helped them avoid relegation in the previous season by performing excellently. If he continues to impress, then there is every chance that he could attract the attentions of big clubs and could make a move to a top team in the future.

Name: Adryan Tavares
Nationality: Brazil

Age: 17 years 
Club: Flamengo
Position: Winger

Adryan Tavares seems to be a top talent and it will not be a surprise if he attracts the attention of clubs all over the world. He is a winger who can play on either side or even in the hole behind the main striker. He scored some excellent goals in the U-17 World Cup recently and has been linked with a move to Manchester United who signed Brazilians Rafael da Silva and Fabio da Silva before the pair had made their Brazilian international debut.

Name: Lucas Piazon
Nationality: Brazil

Age: 17 years 
Club: Chelsea
Position: Attacking Midfielder
Chelsea are going through a period of transition, which is why they have had some inconsistent results this season. With age slowly catching up with Frank Lampard, it is important that Chelsea produce some top talents to replace these stalwarts. In Lucas Piazon and Josh McEachran, the Blues have two very talented youngsters who could be the future of the club. Lucas Piazon was signed from Sao Paulo by the Blue and has already produced some fine performances for the reserve side.

Very nice work. Maybe next one u can include more defenders and goalkeepers?

nice list...nothing to disagree on...

Neymar is overrated; Marcelinho is way better than him.

Can't help but think that if Josh McEachran is on there then surely Jack Wilshere deserves a place... then again, I am biased :D Nevertheless, a great list...

@TPGGunner- Sure Jack Wilshare deserves a place in this list but as I said there are "some" of the promising young players. In the world are too many talented players and I can't add them all in a list so I will make more of them.

@Nico10 : I might see Raphael Varane in your Part II :

he has been promising for madrid this season -

Paul Pogba for Man U.....

and Phil Jones too.

great thread good work, christian eriksen for ajax and mario gotze for b. dortmund are future talents, maybe part 2? good work anyways

Alaba was in the same school like me, just on the other side of the corridor=)

they are all shit, i haven't seen one good player in this post... why would you pick an arsenal youngster you know their all never really improve at arsenal

-Thiago for Barcelona is a real player. His natural understanding of the game is amazing and he has great technique. (as a matter of fact, every up-and-comer for Barca will prove to be a great talent)
-Daniel Sturridge. First impact season for Chelsea. Will and already has boosted his confidence. Great future for the Chelsea winger.
-Eden Hazard (Similar player to Cristiano) when he plays for a big club, he will learn more about the tactical side of the game. right now he scores great individual goals, like Ronaldo did for Lisbon. Next step is to keep scoring fantastic goals, but learn the spaces on the field where easy goals can be scored. This will rack up his tally.
-Coentrao for Madrid. Great attacking full-back and will eventually completely replace Marcelo.
-Jack Wilshere for Arsenal. tough season due to injury. But he will bounce back. When he first started playing for Arsenal, he was their best player under Rvp without a doubt.

Nice list! lol Lucas Piazon look's a bit like kaka! New brazilian icon along with neyamr,pato and hulk?

nice one, but eh probably Willshere can be here too ;)

Maybe Ryo Miyaichi too?

i would suggest eden hazards brother, thorgan hazard!

M'Vila Guys..
he will be one of the best defensive midfielders!

Ahmed Musa plays at CSKA Moscow and Oriol Romeu plays at Chelsea... just sayin

I miss one player: Nélson Oliveira. He's 20 years old and plays for Benfica.
