Lewandowski will sign a four-year contract with a release clause set at €500 million, Barcelona said in a statement.

Lewandowski, who had 12 months remaining on his Bayern contract, moved to Barcelona for €45 million with €5 million in add-ons, the 26-times Spanish champions confirmed.

The 33-year-old has joined the team on their US pre-season tour where he completed his medical.
