Julian Nagelsmann has criticized Barcelona after luring Robert Lewandowski to the club

Nagelsmann is dumbfounded by Barca's ability to sign the Poland international  given their financial crisis.

He added: "I don't know how they've signed so many players.  Barcelona is the only club in the world that has no money, but then buys all the players it wants. I don't know how they do it.

"It's a little awkward, a little crazy, but they have found solutions. They have a better team than last season.

"It was a matter of money. He wanted a challenge and was free in a year. Of course it is snarled and we will miss it. But in the end the operation is not so bad for Bayern."
