The Armenian playmaker joined the Red Devils from Borussia Dortmund last summer and has been a regular fixture in the team under Jose Mourinho.
However, the midfielder made something of a slow start to life at Old Trafford following his transfer in the early stages of the campaign.
Mkhitaryan improved in the second part of the campaign but there is still a sense at Old Trafford that he can further up his game.
And Manchester United legend Yorke believes it will not be long before Mkhitaryan finds his best form for the Red Devils.
Yorke told 888sport: “We’ve seen Mkhitaryan come in and really give the team balance and contribute with goals as well. Unfortunately he hasn’t been able to really kick on due to injuries and the manager’s rotation policy but he’s a really talented player who causes a lot of trouble for defenders when he’s on song.
“The problem is that at Manchester United you cannot have too many bad days without it being noticed and then the critics jump on the bandwagon.
“A first season in the Premier League is always a difficult scenario but he has everything you need to be successful.”
Manchester United finished in sixth place in the Premier League table in Jose Mourinho’s first season in charge as they missed out on a top-four spot in the top flight.
Mkhitaryan scored four goals and made one assist in 24 Premier League games this season.
