Manager Jose Mourinho said: "Henrikh is a very talented footballer, who has been in such prolific form for both his club and his country.
"He is a real team player with great skill, vision and also has a good eye for goal. I am delighted he has chosen to sign for United.

Mkhitaryan has the option of a fifth year which could see him stay until 2021

"I believe he will make an impact on the team very quickly as his style of play is suited to the Premier League. We are all looking forward to working with him."
Sky sources reported late last month that the clubs had agreed the fee, with the player set for a medical following an agreement over personal terms.

Mkhitaryan scored 23 league goals in three years with Borussia Dortmund

Dortmund, who have also lost Ilkay Gundogan to Manchester City, subsequently confirmed they had accepted the offer for Mkhitaryan, who is the current Bundesliga players' player of the season.
Mourinho said on Tuesday that he and the club had identified four key transfer targets - and Mkhitaryan marks the third following the arrivals of defender Eric Bailly and striker Zlatan Ibrahimovic.
