Shocking move of the day. pic.twitter.com/kBQAkgQyLt— Fabrizio Romano (@FabrizioRomano) August 31, 2021The move will end Griezmann's turbulent time at Barcelona, with the 30-year-old seemingly struggling to find his feet at the club since his move worth €120 million back in 2019. Since moving to Barcelona in 2019, Griezmann has been a pale version of his former self, having dazzled with Atletico Madrid for five seasons prior. The Frenchman had scored 133 goals in 257 matches across competitions for Atletico, which earned him a place at Barcelona. However, in his two seasons at the Catalan club, Griezmann has only managed to muster 35 goals in 102 appearances. Barcelona and their fans will not be pleased with the transfer window the club has had, having lost their biggest player of all time in Lionel Messi, as well as Ilaix Moriba and now Antoine Griezmann. Despite signing the likes of Emerson Royal, Sergio Aguero, Memphis Depay, Eric Garcia and Luuk de Jong, the club and its fans will feel like they've got the short end of the stick in this window. There is, however, one major positive Barcelona can take from Griezmann's departure. Antoine Griezmann's massive wages will no longer be on their books, with Atletico Madrid reportedly agreeing to pay Griezmann's wages in full. This is certain to alleviate Barcelona's ongoing financial crisis which forced them to let Lionel Messi go.

If not we should’ve taken a little more time to get these things done before announcing that he can’t continue.— 𝙸𝚜𝚑𝚊𝚚 (@FCBImir) September 1, 2021Griezmann’s departure is symbolic more than anything else. He’s the latest player in Bartomeu era bought 2 years ago who cost us more than $100 million with insane wages.
