Bayern Munich goalscorers Bastian Schweinsteiger and Arjen Robben insist the Bavarian giants must improve ahead of Tuesday's UEFA Champions League qualification, second-leg match at FC Zurich.
Bayern beat the Swiss side 2-0 at Munich's Allianz Arena on Wednesday night in the first-leg qualifier with Schweinsteiger's early goal calming the hosts' nerves before Robben curled in a superb strike on 72 minutes.
Munich will host the 2012 Champions League final on 19 May next year and Bayern are hoping Wednesday's win was the first step on their path to lifting their first European title since 2001.
Even though they dominated the game, Bayern failed to convert at least four clear chances in the second-half as they battered the Zurich goal. Having set up Schweinsteiger for the first goal and then adding one of his own, FIFA World Cup™ finalist Robben was in exceptional form against the Swiss, but says Bayern must raise their game.
"We must be satisfied: a 2-0 win is a good result and we scored two goals, without conceding any," said the 27-year-old former Chelsea and Real Madrid star. "However, we are still not playing well enough and must improve. When we attack, we need to go forward faster and be more aggressive."
Robben was back in the starting line-up after missing Saturday's late 1-0 win at Wolfsburg with a back injury and injected some purpose into the Bayern attack. Germany striker Mario Gomez squandered two clear second-half chances to score while French winger Franck Ribery hit the post with a free-kick and captain Philipp Lahm had his shot saved.
"The result is good for the return leg, but we could have scored two or three more goals," said Schweinsteiger. "We started the game well, but then dropped the tempo. In the second half, we dominated and should have won by more. Zurich will try everything in the return leg and we must give everything against them."
Bayern face Hamburg in the German league on Saturday, but goalkeeper Manuel Neuer says Munich must raise their game with tougher tests ahead this season.
"We know that we have to improve and convert more of our chances," said the Germany star. "Until we scored our first goal, we played with purpose and creativity, then we relaxed a bit. That will be punished against better teams."
