Barcelona have completed the signing of French superstar for a €120 million transfer fee.

“When I was a boy, my dad taught me that trains don't come around just once,” said Griezmann. “Now it's time to take on the challenge of a new destination. Finally, our paths cross. I'll defend the Barca colors with all my determination and commitment. It's our time.”

Griezmann sets a record-breaking release clause

Griezmann's contract contains a Barcelona-record €800 million release clause, €100 higher than the great Lionel Messi.

The transfer saga may go on, however. Atletico Madrid contested the €120m fee, saying that the agreement predates the reduction in Griezmann's buyout clause on July 1. Madrid demands an additional €80 million.

Griezman is the second largest signing of the summer, behind Atletico's acquisition of 19-year-old Joao Felix for a club-record €126 million deal.
