Barcelona are currently in a financial crisis, and according to SPORT, the signing of Antoine Griezmann in 2019 was the move that ruined their financial situation. They had previously funded transfers for Philippe Coutinho and Ousmane Dembele from Liverpool and Borussia Dortmund respectively. Both the deals were worth over €100 million, and so was the transfer for Griezmann.
The Atletico Madrid striker had a release clause worth €120 million in his contract that had to be met in one go. The transfer was expected to be a success for the manager of the club at the time, Ernesto Valverde.
However, Griezmann struggled to deliver in his first couple of seasons at Camp Nou. Moreover, the fact that Griezmann had rejected a transfer to Barcelona a year ago in controversial fashion made it difficult for fans to accept the arrival of the France international.
