Borussia Dortmund would not be open to re-signing Henrikh Mkhitaryan in the future, according to CEO Hans-Joachim Watzke.

Nuri Sahin, Shinji Kagawa and Mario Gotze have returned to Dortmund in recent years.

"Any intelligent player should consider in advance what kind of environment they are moving to," said Watzke. "When you are playing in surroundings where things are working for you, like in Dortmund, then it is quite strange to give that away again once things have finally started to work out for you after a long time settling in."

Dortmund also sold Mats Hummels to Bayern Munich and Ilkay Gundogan to Manchester City.

"We need to cope with losing two world class players in Hummels and Gundogan and also Mkhitaryan," Watzke said.
