Help me out with this...

Which of the following cities in Europe is the best to visit as a football fan? Which one will give you the best experience in terms of football?

Roma of course!

If you can, do share experiences, or give some advice, ideas or so on what the city has to offer a football fan.

Derby della capitale for sure!

In terms of football London. Every stadium is pretty much connected by underground tube or overground train. You also have other dedicated stadiums for Rugby 🏉 (Twickenham) and cricket 🏏 (Lords). Also it’s damn expensive for what you spend other than on the game itself so save up.

I think also Barcelona is good

Marseillle mon pote ;p

J'aime bien Marseille...sauf l'OM ;)

Ive only been to a few of those but in the end it is a matter of preference. If you are asking which city lives football in an intense day to day basis, maybe Istanbul? (never been to Turkey). I know from Experience Milan is very football prone but cities like Barcelona, London, Rome and Paris have just a shit ton of tourists around which kill the atmosphere.
