Hertha Berlin coach Pal Dardai admits he's prepared to see Marvin Plattenhardt sold.
The Germany World Cup defender is a target for a raft of Premier League clubs and negotiations are expected to intensify over the weekend with Plattenhardt back home after his extended summer break.
Dardai said, "Well, I really enjoy working with Marvin. But should he leave, then I think all sides are happy.
"Now he's here, so I plan with him. Of course, there is a pain threshold (price)."
