Bayern Munich winger Arjen Robben has urged his teammates to keep their concentration in games after a number of close-run matches in succession.

Bayern edged past Bayer Leverkusen at the weekend, following the narrow win over Fortuna Dusseldorf and defeat to Arsenal, with Robben suggesting that the Germans must start imposing themselves more on games.

"We played well in the first 20 to 30 minutes [against Bayer Leverkusen] when we dominated the match," Robben told the club's official website.

"Unfortunately, we again loosened our grip after that. Leverkusen improved too, and put us under a lot of pressure.

"Overall it was a step in the right direction, but there were spells when we forgot to impose ourselves on the play. We have to work on that."

Bayern are 20 points clear at the top of the Bundesliga.
