Borussia Dortmund CEO Hans-Joachim Watzke has admitted Henrikh Mkhitaryan could leave the club this summer. The 27-year-old midfielder is understood to be a target for Manchester United, and while the Bundesliga giants have previously insisted they will not sell him, Watzke has now suggested their position has changed.

The Armenian international is out of contract next summer and Dortmund know they risk losing him for nothing in 12 months' time if he opts against signing a new deal. United have reportedly tabled an offer of around £30m (£39.6m) for his services and Watzke admitted the club are considering their options.

"We will assess his situation this week," he said of the reported United transfer target, according to Kicker. The club chief also revealed Dortmund will look to resolve the situation before the team returns for pre-season training on 4 July.

"We not only need to discuss it with [sporting director] Michael Zorc and [coach] Thomas Tuchel, but also with the bodies," Watzke said amid United's apparent interest. "It is a difficult decision."

Dortmund have already sold defender Mats Hummels to Bayern Munich and midfielder Ilkay Gundogan to Manchester City this summer. Watzke said there are a number of factors they must consider before they decide how to resolve the Mkhitaryan situation.

"There are three perspectives with every transfer: An economical, a strategic and a sporting. If the economical side becomes overwhelming, it might happen that you make a different decision in the end," he explained.

New United boss Mourinho is reportedly looking to add pace to his midfield and has identified Mkhitaryan as a prime target. However, any move for the Armenian is likely to put a cloud over the future of Juan Mata, who was sold by Mourinho during his second spell in charge of Chelsea.
