West Ham United are allegedly lining up a summer bid for Manchester United goalkeeper Sam Johnstone.
Hammers boss David Moyes has identified the 25-year-old stopper as a potential replacement for veteran Joe Hart, according to The Mirror.
Johnstone has spent the current campaign at Aston Villa and has impressed in the Championship, playing a key role in the club's promotion bid.
West Ham are said to be willing to pay around £4m for the goalkeeper's services.
Villa, meanwhile, have been tipped to launch a bid of their own at the end of the season to make Johnstone's stay at Villa Park permanent.
