Borussia Dortmund's Kevin Grosskreutz has hailed Bayern Munich winger Arjen Robben as "world class".

The BVB man feels that the Dutch international is one of the elite wingers on the planet, and singled him out as one the biggest threats to his side ahead of this Saturday's German Cup final.

He told Kicker: "Robben is a world-class player. He can, as we know from experience, decide a game on his own.

"To stop him, you have to double him. I always track back a lot and help my colleagues. I know how Robben plays on his side and we will support, for example, Marcel Schmelzer as best we can.

"To be compact and finish our counterattacks with the same precision as we did five weeks ago would be very helpful."

Bayern Munich were crowned Bundesliga champions in record time back in March.
