Robert Lewandowski, Barcelona’s new striker, said he feels fitter now, aged 33, than he did nearly five years ago, and hopes to help the team with his technical ability and experience.

The Polish attacker, who scored 344 goals for Bayern Munich in 375 games, joined Barca in a 45 million euro ($45.80 million) deal last month and was unveiled in front of thousands of fans on Friday at the Campo Nou stadium with his jersey number nine.

Lewandowski, who will turn 34 this month, said age doesn’t matter to him as he faces this new challenge.

“My age doesn’t matter. It’s just a number. I don’t feel like I’m 34 (…) Physically I feel very good and I’ve been at the highest level for many years, we don’t have to think about this,” Lewandowski told reporters.

Lewandowski and the Bayern managers criticized each other for the way they handled the transfer.

“The transfer has not been easy. I have spent eight years at Bayern. But for me and my family it was the perfect next step in my life and in my career. We have worked hard to make it happen, this has been the best solution and I am very proud,” he said.

With Bayern, Lewandowski won eight editions of the Bundesliga, three German Cups, the Champions League and the Club World Cup, among other titles.

The second top scorer in the history of the Bundesliga, behind the late Gerd Müller, assured that he will use his experience to guide Barça’s young players.

“This team has a lot of potential and everything is going well in training. We have to show from the beginning of the season that we are on the right track”, he stressed.
