(CNN) -- Arjen Robben scored twice on his debut as Bayern Munich gave new coach Louis Van Gaal his first victory with a 3-0 crushing of German Bundesliga champions Wolfsburg on Saturday.

Two-goal Arjen Robben made an immediate impact following his transfer from Real Madrid.

The Dutch winger netted both goals in the second half to add to Mario Gomez's first-half opener at the Allianz Arena.

The victory left Bayern five points behind new leaders Bayer Leverkusen, who went three points clear after four games with a 2-1 victory at home to Bochum earlier on Saturday.

Visiting Wolfsburg crashed to a second successive defeat, having lost 4-2 to Hamburg last weekend.

Armin Veh's team went behind in the 27th minute when Germany striker Gomez pounced for his second goal of the season after Diego Benaglio could only parry Hamit Altintop's long-range shot.

Van Gaal brought on Robben, signed during the week from Spanish big-spenders Real Madrid, at the start of the second half.

His first goal was set up by fellow substitute Franck Ribery in the 69th minute, with the Dutchman's shot taking a slight deflection off Andrea Barzagli.

Wolfsburg striker Edin Dzeko hit the post in the 72nd minute and his fellow frontman Grafite had an effort cleared off the line by Philipp Lahm soon after.

But Robben settled Bayern's nerves in the 81st minute from a counter-attack, with France star Ribery again involved.

Leverkusen trailed Bochum in the 32nd minute when Manuel Friedrich put the ball into his own net, deflecting Joel Epalle's shot past goalkeeper Rene Adler.
