Sunderland will reportedly reject any bids for young goalkeeper Jordan Pickford in the summer.
It is believed that Manchester United had scouts at the recent Toulon Tournament to watch the England Under-21 international in action.
Recent speculation has claimed that the Red Devils have identified the 22-year-old as a potential long-term replacement for David de Gea.
However, according to the Sunderland Echo, the Black Cats have no desire to let their academy product leave ahead of the 2016-17 campaign.
The report adds that manager Sam Allardyce has informed Pickford that he will challenge Vito Mannone for the No.1 shirt at the Stadium of Light next term.
