The 2-0 victory over Hannover on Saturday cemented Leverkusen's place in the top three, just one point shy of Borussia Dortmund and defending champions Bayern Munich.

"We give everything that we can in every game and we try to improve the team in training on a daily basis, and we have to work hard for our results," he said.
