Henrikh Mkhitaryan must 'do more' at Manchester United, says Jose Mourinho

Mkhitaryan, 27, was expected to play a key role at Old Trafford following a highly-successful three-year stint with German side Borussia Dortmund, however, the midfielder has thus far largely been sidelined by Mourinho.

"He [Mkhitaryan] has to do more, it's as simple as that," Mourinho told reporters after United's 2-1 Europa League loss to Turkish side Fenerbahce on Thursday.

"We have big expectations at this club, lots of players for these positions, and he has to play better than [Juan] Mata, [Jesse] Lingard, [Anthony] Martial -- he has to play better than them. It's as simple as that.

"Every manager wants to win matches, every manager in the world wants to play the players that he thinks can help the team more, and I'm no different."

So far, Mkhitaryan has made only six appearances for United, five of which were from the bench.

United, who are eighth in the Premier League, travel to the Liberty Stadium on Sunday to face 19th-placed Swansea City, in what will be a must-win match for under-fire Mourinho.
