"Alone, you can win a game, but with the team you win titles.

"No matter who I play against, I always try to score goals. The Bundesliga is not an easy league, you also have to give it a physical boost, you always have to be ready."

Bayern boss Niko Kovac said of the match: "We controlled the game for 90 minutes. We made no mistakes. (It was) a good game."

Summer signings Philippe Coutinho and Ivan Perisic both made their debuts, and the Brazilian forward was impressed with the performance of his new club.

Coutinho said: "I am very happy about my debut. We won, so it was a nice evening.

"The first impressions are good. The game is very intense here. I have only been here three or four days and I'm sure I have to improve. I will work hard."

Schalke coach David Wagner believed his side's efforts were worthy of a goal but acknowledged Bayern deserved the win.

"In the end it was a deserved victory," said Wagner. "Lewandowski has shown why he is one of the best. My team did well in the second half. We would certainly have deserved a goal."
