Borussia Dortmund face struggle to keep Lewandowski
Borussia Dortmund face an even tougher fight to retain the services of their 24-year-old striker after his star performance against Real Madrid

His four goals in the Champions League rout of Real Madrid and expiring contract make Borussia Dortmnd striker Robert Lewandowski a hot target for Europe's top clubs, but the German club have vowed to fight to keep their Poland star.
Lewandowski's record haul against Real at Signal Iduna Park in Wednesday's 4-1 first-leg win made him the first player to score four goals in a Champions League semi-final, and left Dortmund on the verge of their first European final since 1997.
The 24-year-old's Dortmund deal expires in June next year, and he has already said he will not be signing an extension, having joined Dortmund in 2010. But his adviser, Maik Barthel, has said Lewandowski will leave this June.
"We are in agreement with a club and have the right to change this summer," Barthel said. "There is a very interesting offer for Robert, which corresponds to the obligations imposed by [Borussia Dortmund] in full and satisfies Robert's demands.
"[Dortmund have] assured us that Robert can change clubs at the end of the season, under these conditions. We will adhere to the agreement, now the clubs must provide clarity."
