Campbell has refused to pen a new deal at City, leaving West Ham optimistic that they will be able to bring the youngster to the Olympic Stadium.
Campbell is still only 16-years-old, but he has shown a lot of potential while playing for City’s youth team.
It is suggested that the reason behind the striker’s rejection of a new contract at the Etihad Stadium is because he fears about his development.
City have had a tendency to buy for their first-team, rather than promote the youngsters breaking through their youth system.
Campbell feels that West Ham will be more likely to give him the senior football he craves, if he can continue to impress.
If Campbell does make a move from Manchester City to West Ham, he will follow in the footsteps of Martin Samuelsen, who made exactly the same switch.
