The Armenian midfielder will join Jose Mourinho’s team after turning down a new contract at the Westfalenstadion.
Mkhitaryan has 12 months left on his current contract and could leave on a free next summer. Therefore, Dortmund have decided to cash in on the Bundesliga star now.
Dortmund executive Watzke confirmed earlier this week that a decision will be made on the player’s future soon and that Manchester United have submitted a considerable offer for him.
According to latest reports, Dortmund are very unhappy with the player’s behaviour. Mkhitaryan and his agent Raiola have forced Dortmund into selling.
