talkSPORT 7 years ago England 10 0 Chelsea are preparing to raid Barcelona for one of their most promising young stars. According to respected Spanish paper AS, Andre Villas-Boas is set to make 17-year-old sensation Gael Etock his first signing at Stamford Bridge. The La Liga champions were confident the Cameroonian teenager was destined for a long career at the Nou Camp but the west London club have apparently secured the young striker on a four-year deal. It has been reported that the switch will be officially completed on July 5 when Etock, who arrived at Barca via Samuel Eto'o's soccer school, turns 18. But Blues fans will not get the chance to see the prospect at Stamford Bridge until the 2012-13 season as he will join Sporting Lisbon for this season to aid his development.
