Henrikh Mkhitaryan "has to do more" to win his place in the Manchester United lineup, Jose Mourinho says.
The summer signing came into the Europa League defeat to Fenerbahce on Thursday with United chasing the game in the second half.
It was his first appearance for United since facing Man City on Sept. 10, when he came off at half-time, and Mourinho said the Armenian was still not meeting expectations.
"I'm not thinking about sending him off, but he has to do more -- it's as simple as that," Mourinho said in his postmatch news conference.
"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."
With Ander Herrera suspended this weekend, Mkhitaryan could see another opportunity against Swansea if Paul Pogba can not recover from the knock he took on Thursday.
