Cristiano Ronaldo
Ronaldo has enjoyed a remarkable career but there’s no denying his moments of bad sportsmanship. The Portuguese icon has a reputation for diving and pretending that he has an injury. Furthermore, he hates when things don’t go his way and left Manchester United in 2023 under a dark cloud (via SportsJoe).

The truth is that he can be incredibly selfish as he showed in 2018. Gareth Bale scored from an extraordinary overhead kick in the Champions League Final against Liverpool. His teammates celebrated with him but Ronaldo had a tantrum because he wanted to be a penalty. He didn’t care about his teammate’s moment because he wanted to be the hero.
