The Borussia Dortmund sporting director has admitted the Polish striker may leave the club soon, but coach Jurgen Klopp feels the champions will cope

Borussia Dortmund sporting director Michael Zorc says he does not expect Robert Lewandowski to extend his contract.

The Pole’s deal expires in June 2014, and he has been closely linked with a move to Bayern Munich, Manchester United and Juventus amongst other clubs.

The club’s general manager, Hans-Joachim Watzke, claimed earlier this week he believes the 24-year-old would opt to stay, but his colleague does not share his optimism.

“I do not think he will agree a contract extension,” Zorc told Liga Total!.

“We must say this. Apart from that, we are very relaxed and we will be prepared for every eventuality.”

Coach Jurgen Klopp added he was confident his side would be fine should the star striker elect to leave the club.

“If Lewandowski were to go, we are prepared,” he told ZDF.

Lewandowski is currently serving a three-game ban after his red card against Hamburg last week, but Dortmund were able to beat Eintracht Frankfurt 3-0, despite his absence.
