Italian agent Mino Raiola complained about Klopp's people skills that ended with his client leaving the Reds to join OGC Nice.

Apparently, not everyone is fond of Jürgen Klopp's ways with people.

The German boss was criticized by player agent Mino Raiola, who blasted the charismatic manager for mistreating Mario Balotelli, one of his clients.

Speaking to La Gazzetta dello Sport, Raiola couldn't hold back and blasted Klopp for being unfair with the troublemaking striker.

"I don’t think he realised we were talking about a person. Mario was exemplary, he never complained even when training alone. It’s not enough to say Klopp was unfair: he was a piece of sh*t," Raiola stated.

The player agent got into detail about a few conversations he had with Liverpool's execs prior to Balotelli's transfer to Ligue 1 side Nice. 

"At the end of the day the Liverpool directors admitted Klopp was unfair," Raiola added.

Balotelli joined OGC Nice on a free transfer during Deadline Day.

The talented agent also admitted his client's reputation didn't help him while finding another team to play for this summer. Nevertheless, he expects the former Italian international to return to his form of old in the French league.

"It’s natural Balo is considered a risk because over the last two years he has not lived up to expectations. In that sense he’s a gamble, but I’d happily take those odds. I expect 20 goals this season. And if he’s in the same shape as he is now, he’ll definitely get 20," the agent concluded.
