Juan Mata has agreed terms with Manchester United ahead of his £37 million switch to Old Trafford - however the move has been held up while Chelsea complete a deal for Mohamed Salah.
The Spaniard is on the verge of becoming Manchester United's most expensive player, eclipsing the £30.7 million they spent on Dimitar Berbatov in 2008.
According to the Daily Mail, Mata is awaiting his medical result having agreed personal terms the reigning Premier League champions.
The Independent report that Mata will double his Chelsea pay packet and take home £150,000-per-week at Manchester United, and put pen to paper on a five year contract.
However the Red Devils are being made to wait before finalising the deal for Mata as Chelsea try to finalise a deal for Basel forward Mohamed Salah.
Chelsea boss Jose Mourinho confirmed today that the move is being held up as they try and and complete a medical with the Egyptian international.
"He cannot come to England for his medical so we have to travel to meet him, probably in Switzerland, and only after that we can get the paperwork to bring him to the country," confirmed the Portuguese boss.
Manchester United will hope to get the deal wrapped up before their Premier League game against Cardiff on Tuesday.
Mata has struggled for first team action under Mourinho this season, although the 'Special One' insists that 'no one is jumping' at the prospect of his departure from Stamford Bridge.
'Juan travelled and had a medical at United. Things are going in a good direction so sooner rather than later things will be finalised,' he said.
'I still think he could be important for us - he is a fantastic player. Despite not playing a lot with us, especially in the last period, he could (have been) important.
'Nobody here is jumping because Juan is leaving. After that, it’s the way you look at things. Would Chelsea supporters be happy if we stop a fantastic person they all like a lot from going and say you can only go if you go to Russia or China or France or Portugal?
I don’t know if Chelsea supporters would be happy because we are an open club. We don’t have an old-fashioned way to look at things.
'But Juan had a fantastic opportunity. Another big club wants him in a country where he loves to be. We had an offer which was the right offer a player of his quality.
'The player deserves respect and to be happy - to play where he wants.
To say you cannot go to United because they refused to sell us Wayne Rooney isn't fair to Juan. They decide not to sell, their decision.'
