The German winger says that Borussia Dortmund are brave and do not fear the champions as many other teams do but feels that they will have to double up on the dangerous Dutchman
Pep Guardiola's side meet BVB on Saturday as they look to record a domestic double following their Bundesliga success.
Although Dortmund inflicted a 3-0 defeat upon the Bavarian giants at the Allianz Arena in April, Grosskreutz is wary of the threat that Bayern pose, Robben chief among their dangers.
"Robben is a world-class player," he told Kicker. "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."
The German winger added that BVB will have to be compact and clinical if they are to beat their rivals but says that Dormtund do not fear Bayern like most teams in the Bundesliga.
"To be compact and finish our counterattacks with the same precision as we did five weeks ago would be very helpful," he declared.
"In the Bundesliga, there aren't many brave teams when they are dealing with Bayern. We play brave, we are not afraid, we do our thing."
