Henrikh Mkhitaryan is convinced he can shine at Manchester United and has heaped big praise on Jose Mourinho's coaching record.
The Armenia midfielder has failed to impress at Old Trafford since his summer arrival and has not started a game since aggravating a thigh injury in the defeat by Manchester City in September.
Despite reports linking him with a swift return to former club Borussia Dortmund, he has revealed his determination to fight for his place on the Football Federation of Armenia's website.
Mkhitaryan, who played in the whole of his country's dramatic World Cup qualifying win over Montenegro in Yerevan on Friday, said: "I know I can succeed at Manchester United, and I want to show everyone that I deserve to be a key player in this team and this league.
"Today I don't have enough playing time, so I have to do my best so the coaching staff give me the chance to play.
"There are no disappointments, just challenges. I never give up when I encounter obstacles in my way. I just continue going until I reach my career objectives."
The 27-year-old was a £27.3m buy from the Bundesliga club but has been sidelined by Mourinho, who has repeatedly stated he needs time to adapt in the Premier League.
But despite the apparently difficult relationship between the pair, Mkhitaryan said: "Regarding Jose Mourinho, I hope I can learn a lot from him - he is a coach with a fantastic record.
"I saw the move to Manchester United as an opportunity to grow as a player and as a person.
"It was definitely not the salary that made me join Manchester United, I went for football reasons - for the history of the club, the fans and the coach because he is one of the best in the world.
"The EPL is the best league in the world and it gives me something different, a new challenge. I think I can become stronger by playing there."
