Robert Lewandowski admits he has no regrets leaving Bayern Munich for Barcelona.

The Pole, however, feels Barca still need to strengthen the team for next season.

"I'm very satisfied, the step was exactly right," he told BILD, "we feel very comfortable with the family, have a very good chance of winning the championship with Barça, that was our goal. We can also get the Copa del Rey.

"We still need two or three pieces of the puzzle so that the club can function like FC Bayern has for years.

"Then more is also possible in Europe."
