Manchester United have set a £37million asking price for Juan Mata as his Manchester United career hangs in the balance, according to a report.

ESPN claim that Mata is one of 10 United players pushed to the Old Trafford exit door as Mourinho eyes up a defensive leader to complete his summer overhaul.

It is said that the Portuguese boss is looking to raise funds for a centre-back with Leonardo Bonucci from Juventus and Real Madrid’s Raphael Varane the two named players.

Mourinho is willing to sell up to 10 players in order to trim his squad, with Mata, Adnan Januzaj and Bastian Schweinsteiger the most high-profile.

The United hierarchy want to ensure they at least recoup most of the £37.1million they spent on him, with Everton showing firm interest.

This report follows claims from The Times that the Toffees have made an enquiry for the Manchester United attacking midfielder.

Mourinho cast doubt over Mata’s Old Trafford future after subbing the midfielder less than half an hour after bringing him on in Sunday’s Community Shield win over Leicester.

The Spaniard replaced Jesse Lingard during the Wembley clash , only to be hauled off 27 minutes later for Henrikh Mkhitaryan.

Everton have been linked with Mata as Ronald Koeman overhauls his squad using the £100million transfer kitty handed to him by billionaire Goodison owner Farhad Moshiri.

It was Mourinho that sold Mata to United for £37million in January 2014 when he was Chelsea boss just six months after the Spaniard had been named the club’s player of the year for the second consecutive campaign.

Mata has been an integral member of the United team since joining the club and was a first-team regular under previous boss Louis van Gaal.

Used predominantly on the right flank, Mata made 54 appearances in all competitions for the Premier League giants last season, scoring 10 goals and supplying 11 assists.

In other Everton transfer news, David Moyes has claimed Lamine Kone will be offered a new Sunderland contract.
