According to the Telegraph, Man United have agreed terms with Juan Mata on a four-and-a-half year contract, but the Spaniard has been left frustrated by Chelsea's reluctance to finalise his move.
It's thought that Jose Mourinho will only sanction the transfer once he has secured the signing of Basel winger Mohamed Salah, who is also a target for Liverpool.
Chelsea yesterday confirmed they had agreed a fee with the Swiss club for Salah, even though he is a player Brendan Rodgers has been chasing for several months.
Rodgers was on talkSPORT this morning where he confirmed that Liverpool were still in the race to sign the 21 year-old Egyptian international.
Mata had been due to undergo a medical in Manchester on Thursday, which has been delayed by Chelsea's reluctance to push through the deal.
Man United are thought to be calm and confident of securing their record signing within the next 48 hours, while Mata himself is said to be determined to become a United player as soon as possible.
