In 2013, the Armenian midfielder moved from the camp of the "miners" to the German club for 27.5 million euros.
According to Michael Zork, this deal was very difficult to implement.
"Negotiations with Shakhtar on Mkhitaryan are the most difficult in my life," Zork said in an interview with Kicker.
"Everything happened in a strange way. We with the general director of the club Hans-Joachim Wattske arrived in Donetsk.
We talked with the representative of Shakhtar who, after each of our three proposals, left the room to talk with club president Rinat Akhmetov ".
"Akhmetov himself was a hundred meters from the place where the negotiations took place, but we did not see him that way".
Mkhitaryan played in Borussia three seasons, after which he moved to Manchester United in the summer of 2016.
