MUNICH (AP) — Poland striker Robert Lewandowski says that his "batteries are full" and he is looking forward to improving as a player at Bayern Munich.
Lewandowski, who joined the Bundesliga champion on a free transfer from league rival Borussia Dortmund, said at his presentation Wednesday that his new club is "the yardstick, the club where I can win many titles."
Lewandowski scored 74 goals and set up 31 more in 131 Bundesliga games for Dortmund since joining from Polish side Lech Poznan in 2010.
He helped Dortmund claim the Bundesliga in his first two seasons at the club, as well as the German Cup in his second, though the side finished runner-up to Bayern the past two seasons.
"I was four years at Borussia. I knew it was time to make the next step," he said. "I know that every new player needs time but I hope the transition won't take long for me and that I'll be able to give my best from the first game."
Lewandowski missed out on the World Cup after his native Poland failed to qualify but that may prove beneficial for Bayern.
"I feel very well. I had a lovely holiday and my batteries are full again," the 25-year-old said.
Lewandowski, whose contract expired in the summer, signed a five-year-deal with Bayern in January, before completing the season with Dortmund.
Dortmund had declined the opportunity to let the forward leave for a transfer fee last summer, after failing to reach an agreement on extending his deal.
"He delivered extraordinary performances in Dortmund even though the transfer was already fixed," said Bayern sporting director Matthias Sammer. "That's the stuff champions are made of."
Lewandowski follows attacking midfielder Mario Goetze as the second key player to switch from Dortmund to Bayern in as many seasons.
Also Wednesday, Sammer confirmed that Croatian striker Mario Mandzukic, who would have been competing for a starting place with Lewandowski, was set to leave Bayern for Atletico Madrid.
