Cooper has already been the subject of interest from another club, Everton, but Sheffield United rejected their approach earlier this summer. Now, West Ham is trying to make contact with Cooper's team to discuss a potential transfer.
The transfer fee that West Ham is willing to pay for Cooper is reportedly £15 million. If Cooper joins West Ham, he will be competing with Alphonse Areola for the starting goalkeeper position. There are some doubts about Areola's status as the team's first-choice goalkeeper, and manager Graham Potter may be looking to shake things up by bringing in a new player.
