An angry Lionel Messi reportedly waited for over an hour in the players’ parking lot to insult Real Madrid assistant coach Aitor Karanka and defender Alvaro Arbeloa following Wednesday’s 1-1 Copa del Rey first-leg clash between FC Barcelona and Los Blancos.

Real winger Jose Callejon says he was talking to reporters about this weekend’s game away to Granada when he overheard Messi call Karanka coach Jose Mourinho’s “puppet.” He said: "I saw the incident with Aitor because I was coming along behind [Messi]," Callejon said. "I do not know if he called him a name, but he did say that Karanka was Mourinho's puppet.”

Callejon could not confirm what had happened with Arbeloa, but according to reports, Messi insulted the former Liverpool man in front of his pregnant wife. “On the field tempers can flare and you can understand because we all say many things and we can use insults, but when a fellow professional waits an hour after the game to dress down another professional, with his wife beside him, it shows that the good guys are not always so good, nor the bad guys so bad," Callejon said.
