"?Sky Sports pundit Jamie Redknapp says that Manchester United's Juan Mata is likely to leave the club when Jose Mourinho is appointed manager.
Mourinho is expected to be named as United's new boss after Louis van Gaal was reportedly sacked on Monday, despite the Dutchman winning the FA Cup on Saturday.
The Portuguese manager worked with 28-year-old Mata when the pair were at Chelsea, but the ex-Real Madrid and Inter Milan man sold the midfielder after rumours that Mourinho did not consider the Spain international's work ethic was good enough to flourish in his preferred footballing system.
Mata scored the Red Devils' equaliser in Saturday's 2-1 triumph over Crystal Palace at Wembley and helped them secure their first trophy of the post-Sir Alex Ferguson era in the process.
Writing in his column for the "?Daily Mail, however, former Liverpool player Redknapp believes that Mata, along with the likes of Michael Carrick and Marouane Fellaini, will depart Old Trafford in the summer as Mourinho will deem the trio not good enough for a club of United's stature.
"Juan Mata has done well for United and scored some important goals "? not least in the FA Cup final," Redknapp wrote.
"But Mourinho let him go at Chelsea and I wouldn't have thought the Spaniard is in his plans.
"Michael Carrick is not getting any younger, and while he did well in the FA Cup final, Marouane Fellaini is not good enough for United.
"They need a top-class player like Arturo Vidal or Paul Pogba to run that midfield.
"You look at Jose's title-winning midfield at Chelsea of Michael Essien, Frank Lampard and Claude Makelele and United are a long way off that."
Mata joined United for a fee of around £37.1m, and has 26 goals and 20 assists in 104 appearances for the 18-time English league champions.
