Manchester United have reportedly had a player-plus-cash offer for Issa Diop turned down by West Ham United.
According to The Mirror, United offered £40m plus an unknown player to West Ham, but the Irons have knocked them back.
Diop joined the London side from Toulouse in a £22m deal last summer and the report indicates that they are determined to keep hold of him.
However, the player himself could hand in a transfer request to force through a move to Old Trafford.
If that is the case, West Ham would still allegedly hold out for £60m as Diop has four years to run on his contract.
