Mohamed Salah and Sadio Mane's recent spat made the headlines, but the duo insisted all has been resolved. However, there were many other teammates whose relationship was a lot worse, with Zlatan Ibrahimovic once even threatening to break a teammate's legs!
Click through the gallery above to see some teammates who hated each other, according to FourFourTwo.
Ibrahimovic and his former Ajax Amsterdam teammate Rafael van der Vaart seemingly became enemies during an international clash between Sweden and the Netherlands in 2004.
The latter blamed his outspoken teammate for an ankle injury, but Ibrahimovic did not respond well to claims that he injured his club colleague on purpose.
"I didn't injure you on purpose, and you know that," he said at the time, as quoted by FourFourTwo.
"And if you accuse me again I'll break both your legs – and that time it will be on purpose."
Over in Germany, Lothar Matthaus and Stefan Effenberg played alongside each other at Bayern Munich and for their national team in the 1990s.
However, Effenberg once claimed that Matthaus "lacked courage" for not taking Germany's penalty in the 1990 FIFA World Cup final, while the legendary midfielder reportedly suggested that Bayern get rid of Effenberg following a defeat to Hansa Rostock in 2001.
The duo never really repaired their relationship, with Effenberg even dedicating a chapter in his autobiography to Matthaus. It consisted of a blank page headlined: "What Lothar Matthaus knows about football."
In Italy, Mauro Icardi and Maxi Lopez turned from foes into enemies after the former went after the latter's ex-wife Wanda Nara and ended up marrying her.
They used to be best buddies at Sampdoria, but Lopez never forgave his friend, with their hatred being highlighted when they met as opponents for Inter Milan and Torino, and Lopez snubbing a handshake from Icardi.
