​Borussia Dortmund defender Sokratis Papastathopoulos has claimed that wantaway star Ousmane Dembele must behave professionally instead of dong whatever he wants.

Dembele has been absent from training for the past week as he looks to complete a move to Barcelona and this has angered Sokratis, who has implored the youngster to follow Pierre-Emerick Aubameyang's example.

Aubameyang has been linked with a move away from Borussia Dortmund but according to Sokratis, the Gabon striker has acted professionally instead of going AWOL.

Speaking to Kicker, as reported by ​FourFourTwo, Sokratis said, "Ousmane is a good guy. But he has to understand that no player is bigger than the team. Everyone has to understand that he has to work for the team and fall in line. This also applies to Ousmane."

"He can't do whatever he wants and should take Pierre-Emerick Aubameyang as an example. Auba also could imagine leaving. But he behaves professionally in every training session and every game and gives his best."

"In the first round of the cup he scored three goals, Ousmane wasn't there. Ousmane has done no good by going on strike. He should not forget that he still has a long-term contract at Dortmund," he added.

On asked whether he saw Dembele returning and playing for Dortmund, Sokratis was skeptical, stating that the Frenchman has to return to training first.

Sokratis added: "At first he has to get in touch with us and come to training again. Then we will see. Ousmane has given us very much. He is a player who makes the difference. We need players like this."

"But we also need players who don't exclude themselves and who want to be part of our family. Apparently Ousmane doesn't want that," the Greek defender said.

Dembele is close to a move to Barcelona and decided to skip training last week, for which he has been suspended by the club. The former Rennes man is reportedly not in contact with the German side and looks set to make an acrimonious departure from the Signal Iduna Park outfit.
