The prodigiously talented midfielder was linked with a move to Arsenal and Manchester United as well.
The 16-year-old Portuguese midfielder was frustrated with the lack of chances at Chelsea and believes that he can progress with a move away from Stamford Bridge.
Manchester United and Arsenal were both linked with the player. Both clubs have a great track record of relying on youth and it was reported that Quina felt that he has a better chance of making the grade at those clubs.
The Portuguese midfielder is regarded as one of the best players of his age in Europe and his goalscoring ability at this age has attracted a lot of interest from other European heavyweights as well.
Quina has already been capped by Portugal at the Under-17 level and has been a key part of Chelsea’s youth set-up over the last three seasons after being recruited from Benfica.
According to reports from Daily Mirror earlier, Manchester United were preparing a bumper offer for the talented midfielder and will offer him a package that will be hard to refuse.
But now the player has confirmed the move himself on his Instagram profile. He was pictured signing a contract in a West Ham United shirt.
