BVB Dortmund legend Karl-Heinz Riedle has labelled in-form Bayern München forward Robert Lewandowski as the best striker in the world.
The Poland international has been in scintillating form for Bayern recently, scoring 10 goals in his last three games, including five after coming off the bench against Wolfsburg just over a week ago.
Speaking ahead of the Der Klassiker clash between Bayern and Dortmund on Sunday, Riedel warned his former side to pay special attention to the Polish hitman.
"In his position, I think he is probably the best player in the world. He hardly has any weaknesses, he is powerful in the air. He just holds on to the ball like no one else," he told Omnisport.
"He isn't that fast like Aubameyang, that's the difference. Lewandowski is just another type of centre-forward than Aubameyang.
"In my opinion, Pierre-Emerick is more of a counter-player than Lewandowski."
Dortmund have had an impressive start to the season under new coach Thomas Tuchel after the disappointment of last term, which resulted in the resignation of Jurgen Klopp.
"Of course everybody was shocked when Jurgen Klopp quit – he characterised the club over the last eight years like no one else did," Riedel added.
"So it's difficult for every coach who comes after him. But Thomas Tuchel accepted the task, it's a chance for him.
"A lot of people were wary because he hasn't got the temperament of Jurgen Klopp. But he is a very good analyst and a great technical coach. A different person than Klopp, of course," he concluded.
