Back in 2020, Barcelona decided they didn't need Luis Suárez anymore, so they sold him to Atlético Madrid for just £6.5M. Ronald Koeman even broke the news to him over the phone.
"The call from Koeman to tell me that he didn't count on me lasted 40 seconds, it's not the way to fire a legend. First he told me that I was not in his plans and then he told me that if I did not resolve my contract I was going to play against Villarreal. He lacked the personality to tell me things clearly, if he didn't want me or if it was really the club that didn't want me."
He went onto score 21 goals and led Atleti to the league title for the first time in 7 years. Oh, and when he scored against Barcelona, he didn't forget that phone call...
