Henrikh Mkhitaryan vowed to "find the strength to reach my goal" when asked about his determination to impress for Manchester United at a UNICEF event on Wednesday.
The Armenian, currently away with his country, made his first Reds appearance in almost two months and only his sixth since signing in the summer during last week's Europa League defeat at Fenerbahce.
Jose Mourinho believes Mkhitaryan can become a top player for United but said after the 2-1 defeat in Turkey that he "has to do more" to earn a regular starting place, and the man himself insists he will.
