Henrikh Mkhitaryan has refused to give up on his Manchester United dream following a slow start to his career at Old Trafford.

Mkhitaryan’s lack of game time since arriving at Old Trafford has perplexed many around the club especially after the club paid £26million for his services this summer.

The Armenia midfielder was a revelation for Dortmund last season scoring 18 goals throughout a superb campaign but United fans are yet to catch a glimpse of that sort of form from the playmaker who has mostly been left on the bench by Mourinho.

Mkhitaryan's last performance in a United shirt came during the club’s 2-1 defeat to Fenerbahce in the Europa League last week and when questioned about the ex-Dortmund man after the game, Mourinho simply said ‘he needs to do more’.

And the talented midfielder seems to have received his manager’s message loud and clear after issuing a strong reponse to Mourinho while becoming the a 'goodwill ambassador' for Unicef in Armenia.

"It is true that I get little time on the field, but I am not going to give in," Mkhitaryan said.

"I went a long way to play in Manchester United, so nothing will prevent me from achieving my dream.

"I will not retreat, I will find the strength to reach my goal."

Mhkitaryan, however, isn’t the only United player that is struggling to win over Mourinho. World Cup-winning midfielder Bastian Schweinsteiger had been cast out into the wilderness for weeks by the 53-year-old before returning to training a fortnight ago.

In spite of this, Mourinho is expected to sell the Germany international after telling him he wouldn't be part of his future plans earlier this season.

Mourinho has also questioned the commitment levels of Luke Shaw and Chris Smalling after the pair declared that they were unfit to play in United’s 3-1 victory over Swansea on Sunday.
