Top 5 controversial transfers of the decade

2. Antoine Griezmann: Atletico Madrid to FC Barcelona

FC Barcelona v Borussia Dortmund: Group F - UEFA Champions League

Antoine Griezmann left Atletico Madrid to join FC Barcelona in 2019 for a staggering fee of €120 million. The Frenchman was linked with a move to the Catalans in 2018 as well. But he ended up staying in Madrid after announcing his decision through a documentary named 'La Decision'.

Rojiblancos offered a new contract and captaincy to their star striker in a bid to fend off interest from Barca. But the player eventually decided to quit the club and join Barca.

Even this year, his transfer ended up in controversy as Atletico accused Barca of approaching the player unlawfully. The Madrid based club alleged that Griezmann signed a pre-contract agreement to move to Camp Nou back in March without the knowledge of officials at Atletico.

Barcelona was dragged to the court over the matter and were found guilty of approaching the player without the knowledge Diego Simeone or the club officials.
