It should have been happy hour at PSG. The Parisian giants had just won the French league title for the first time in 19 years.

But instead of it being a joyous occasion, celebrations were marred by a very public spat between star striker Zlatan Ibrahimovic and sporting director Leonardo.

As the players began celebrating in the dressing room after the 1 - 0 win over Lyon, an altercation seemed to occur between the Sweden captain and the former Brazil international... 

Who knows what the argument was about but Leonardo has other things to worry about. The former AC Milan and Inter manager was caught on camera pushing the referee in the tunnel at half-time in their controversial 1 - 1 draw against Valenciennes.

Leonardo faces a lenghty ban and PSG could even see points deducted. Judge the push for yourself...
