The 19-year-old highly rated goalkeeper has just 18 months remaining on his current contract, and both the Manchester clubs are keeping tabs on his current contract situation.
The Hammers are keen to tie down the future of the young stopper and are desperate to hand him a new deal this season.
German side RedBull Leipzig are also reportedly tracking Trott, who remains the Hammers’ third-choice goalkeeper behind Adrian and summer signing Lukasz Fabianski.
Trott has made seven appearances for West Ham’s Under-23 side this season. Terry Westley’s side have conceded 17 goals and the youngster has failed to keep a clean sheet.
The report adds that there were loan offers for the young goalkeeper, but the Hammers wanted to hold on to him to provide cover for both first-team goalkeepers.
Trott is a highly rated young goalkeeper, and he has a better chance of getting into the senior side at West Ham than at either of the Manchester clubs.
