The former Chelsea winger has stressed that his compatriot is the Royal Blues' main attacking weapon, and is desperate to bag all three points in Gelsenkirchen
The striker scored an impressive 29 league goals in 2011-12 and has already netted twice in his side's opening three games this season, and Robben believes that keeping his compatriot at bay will be crucial if the Bavarians are to prosper.
"We must not allow Huntelaar any chances," Robben was quoted as saying on the official Bayern website.
Bayern currently sits second in the Bundesliga table with nine points from three games, and Robben is hopeful that the club can maintain its perfect record versus Schalke.
"It would be great if we could win the next two or three games as well, because we’d be on a really good run."
