Juan Mata is growing increasingly frustrated as Chelsea continue to drag their heels over his £37m transfer to Manchester United, according to the Telegraph.
The Spanish playmaker is on the verge of moving to Manchester United after agreeing a four-and-a-half year deal worth £150,000-a-week.
However, Chelsea are yet to complete their part of the agreement and have not sanctioned Mata's release so that he may take part in a medical.
Reports on Thursday suggested that Manchester United staff had prepared a landing pad especially for Mata's arrival via helicopter, only to be met with silence.
Mata had instead remained in London waiting for Chelsea to wrap up a deal for FC Basel winger Mohamed Salah, believed to be worth £11m.
But Mata is keen to seal an exit to Old Trafford and is growing increasingly frustrated with Chelsea's reluctance to rubber stamp the deal.
Although Manchester United don't play this weekend, David Moyes was hoping to get the 25-year-old involved for the visit of Cardiff on Tuesday. But with the deal not yet going through, it is growing more and more unlikely that Mata will be ready in time.
Despite the delays, the Telegraph report that Manchester United staff are unconcerned and are still confident of wrapping up the deal before the week is out.
