West Ham goalkeeper Trott is one of West Ham's best up-and-coming prospects.
The Daily Mirror claims both Manchester City and Manchester United are interested in signing West Ham United goalkeeper Nathan Trott, and are keeping tabs on his current contract situation.
The 19-year-old stopper has just 18 months remaining on his current contract, with the Hammers desperately trying to tie down the future of the European Under-19 champion.
West Ham will be keen to avoid a desperate fight to keep Trott and agree a new deal this season, with the saga surrounding Declan Rice's future something that should have been avoided.
Both Manchester clubs and German side RedBull Leipzig are said to be tracking Trott, who remains the Hammers' third-choice goalkeeper behind Adrian and summer signing Lukasz Fabianski.
It is believed that Trott was the subject of multiple loan offers in the summer but the Hammers were desperate to keep him on side to provide cover for both first-team goalkeepers.
This season, Trott has made seven appearances for West Ham's Under-23 side this season, failing to keep a clean sheet for Terry Westley's side and conceding a huge 17 goals.
