Manchester United have reportedly named an asking price of £5m for goalkeeper Sam Johnstone.
The 24-year-old is currently on loan at Aston Villa and has kept nine clean sheets in 22 Championship appearances for the Midlands club.
Johnstone has yet to make a first-team appearance for United, however, and according to the Daily Mail, the stopper could be sold by Jose Mourinho in the January transfer window.
The report goes on to suggest that West Ham United, West Bromwich Albion and Crystal Palace are all interested in Johnstone.
In addition, Villa may be forced into selling should they wish to secure the Preston-born custodian's permanent services due to financial fair play regulations.
Johnstone, who came through the ranks at Old Trafford, has 18 months left on his United contract.
