Juan Mata grows increasingly frustrated with Chelsea for stalling transfer to Manchester United

Spain international Juan Mata has agreed a four-and-a-half year contract worth £150,000-a-week at Manchester United but Chelsea are yet to complete the transfer agreement

Juan Mata is still waiting for Chelsea to formally sign off his £37 million transfer to Manchester United after growing increasingly frustrated with the club’s failure to sanction his departure for a medical at Old Trafford.

Despite agreeing a four-and-a-half year contract worth £150,000-a-week at United, Mata remained in London all day yesterday due to Chelsea’s refusal to complete the transfer agreement with the Premier League champions.

There are now suggestions the transfer may not go through until next week.

Ground staff at United’s Aon Training Complex at Carrington had arrived early on Thursday morning to prepare a helipad in order for the Spain midfielder to fly north for a medical.

But with Chelsea delaying Mata’s departure until they had completed the signing of FC Basle’s Egyptian winger Mohamed Salah, United were unable to proceed with the medical examination in Manchester.
