10 Man United players who must prove their worth to Jose Mourinho

JUAN MATA

The Spaniard perhaps has most to worry about from Mourinho's appointment, having been sold to United by the Portuguese in 2014, but while Mata lacks the pace and physical strength to become a key man under Mourinho, his knack of scoring goals in big games may yet play in his favour.

SURVIVAL RATING: 6/10

MARCOS ROJO

The Argentine defender has endured an injury-hit time at Old Trafford since arriving from Sporting Lisbon two years ago. While Rojo possesses the physical attributes of a typical Mourinho defender, his poor concentration ensures his days will be numbered.

SURVIVAL RATING: 3/10

ANDER HERRERA

The £28.8m midfielder is under threat with Mourinho because he lacks a defined role and has struggled to make an impact during two seasons at United. Does not do enough to influence games and could be offloaded this summer.

SURVIVAL RATING: 4/10

DALEY BLIND

The he Dutch defender became a key man under Louis van Gaal, impressing at centre-half last season having also played in midfield and at full-back. Blind may lose his centre-back position under Mourinho, but his versatility will earn him a stay of execution.

SURVIVAL RATING: 8/10

MICHAEL CARRICK

The 34-year-old is out of contract this summer and still waiting t hear if he will be offered a new deal, but his experience and knowledge of the Premier League is likely to see Carrick handed a one-year deal by Mourinho.

SURVIVAL RATING: 8/10

PHIL JONES

Once regarded as a future England centre-half, but Jones has endured an injury nightmare at Old Trafford. But Mourinho likes to build his teams around a core of domestic players and Jones may yet be given the chance to prove himself for that reason.

SURVIVAL RATING: 6/10

BASTIAN SCHWEINSTEIGER

The Germany captain was a major disappointment last season. A Van Gaal loyalist, Schweinsteiger may find life too demanding under Mourinho and appears an obvious candidate to be moved on.

SURVIVAL RATING: 2/10

MAROUANE FELLAINI

Fellaini divides opinion at Old Trafford, with many regarding the Belgian as typifying the worst of Van Gaal's reign, but he is effective and Mourinho is likely to regarded the former Everton midfielder as a useful Plan B.

SURVIVAL RATING: 7/10

MEMPHIS DEPAY

Mourinho turned Arjen Robben into a star during his first spell at Chelsea and Depay arrived at United with a reputation as Holland's successor to the Bayern Munich winger. He had a disastrous first season, though, and needs to improve his attitude to survive under Mourinho.

SURVIVAL RATING: 5/10

ADNAN JANUZAJ

Januzaj became a forgotten man under Van Gaal, but United still believe the Belgian can become a world-class talent. He will be forced to accept Mourinho's tough approach, but it worked for Joe Cole at Chelsea and Januzaj could yet salvage his United career under the Special One.

SURVIVAL RATING: 6/10
