The two midfielders, who played together at Borussia Dortmund, are likely to be competing for a place in Jose Mourinho's side next season.
Manchester United attacking midfielder Adnan Januzaj has tweeted a picture of himself and new signing Henrikh Mkhitaryan, after the Armenian announced his arrival from Borussia Dortmund.
A great indication of a new wave of togetherness, it is good for the 27-year-old that he has a familiar face at Old Trafford.
The two talented midfielders spent a few months together in Dortmund, and even though the Belgium international didn't get as many minutes as he would have liked, it is clear he benefitted when it came to building relationships with teammates.
And Manchester United will benefit in the coming seasons with the 21-year-old able to assist the Armenian star in settling in at Manchester and in the Premier League.
Januzaj turned out 12 times while in Germany, but returned to Manchester in January only to feature three times. Mkhitaryan on the other hand had a phenomenal campaign, scoring 23 goals in 51 matches.

As it turns out, the two may even end up competing for the same position in Jose Mourinho's starting eleven, with the Portuguese said to be a big fan of Januzaj. However, it is very much expected that Mkhitaryan will quickly become an essential part of the United.
