While more experienced domestic champions Barcelona and Manchester United held relatively incident free parades through their respective cities, PSG fans celebrated their first Ligue 1 title since 1994 by busting up shop windows and fighting police.

The riots began Sunday night after PSG beat Lyon 1-0 (which was also followed by Zlatan Ibrahimovic yelling at Leonardo until he ended up in the hospital). They resumed on Monday as PSG held their open-top bus parade through Paris. The parade concluded in front of the Eiffel Tower, where the players lifted the trophy and the fans switched back into riot mode.

PSG finally clinched the Ligue 1 title with a 1-0 win against Lyon on Sunday. This pleased Zlatan Ibrahimovic. But as he celebrated with his teammates in the dressing room after the match, PSG director of football Leonardo attempted to tell Ibrahimovic that he had to go take an anti-doping test. This did not please Zlatan Ibrahimovic.

The players' rallying chant was cut short when Zlatan began shouting at Leonardo in front of everyone, expressing how he didn't want to get held up doing the test while his teammates partied. "You always ruin everything," Ibrahimovic shouted at Lenoardo in Italian.

The wrath of Zlatan aside, he should be pleased with this latest victory, as he has now won domestic titles in Holland, Italy, Spain, and now France. Teammate David Beckham, meanwhile, is the first Englishman to win titles in four countries (England, Spain, USA and France). Here they are celebrating their achievements together in a happier moment...

With the Copa del Rey final to be played this coming Friday, Real Madrid decided to rest a number of regulars during their match against Espanyol. Defender Fabio Coentrao was one of those players not selected for the match, yet he still took a seat on the bench anyway. When his teammates who were supposed to be there caught on to his mistake, they had Iker Casillas inform him. Coentrao gave him the blank stare of a kid who was just asked about a homework assignment he forgot to do before laughing at his error.

Coentrao then went over to assistant manager Aitor Karanka to make sure everyone wasn't playing a joke on him and when he got his response, he immediately left the dugout and headed upstairs. Manager Jose Mourinho then joined in on the chuckles at Coentrao's expense while Cristiano Ronaldo pointed to his head as if to say "he's a dumbbell" upon being informed of what happened. And those two are good friends.

Having seen this, we now realize that one thing is certain: if Karim

After an ideal farewell in his last match at Old Trafford, Sir Alex Ferguson spoke to the seeker of harsh truths himself, Geoff Shreeves. After warming Ferguson up with a couple of softballs, Shreeves asked him why Wayne Rooney watched the match from an executive suite. Ferguson responded by confirming reports that Rooney has asked for a transfer (again) and Shreeves seemed a bit stunned by the straight forward reply. Said Ferguson:

"Well, I don't think Wayne was keen to play simply because he's asked for a transfer. I think he wants to think it through in his mind. I think that's a good idea. We're not going to let him go. And I think maybe he's a little bit frustrated that he's been taken off once or twice in the last few weeks."

On the topic of Ferguson's retirement, Shreeves brought up how unexpected the announcement was. After all, Ferguson has maintained for years now that he would continue as long as his health would allow and even wrote in his matchday program notes a mere

Perhaps driven mad by Milan's garish new gold kit, Sulley Muntari was sent off in just the 40th minute of their match against Roma for trying to physically restrain the referee from showing him a yellow card after booking Mario Balotelli for a late challenge.

As incredibly dumb as Muntari's actions were, the incident was something of a continuation of what he did last week in Milan's match against Torino. Balotelli took his shirt off after scoring late in the second half of that game, earning an automatic caution. But Muntari took the card off the ref and showed it to Balotelli himself before handing it back to its rightful owner. To his credit, the referee laughed it off and went about his business. Here's video...

Watford have reached the Championship playoff final and a chance at promotion to the Premier League after beating Leicester in the most stunning way possible. Leicester took a 1-0 lead into the second leg of the semifinal tie, but Watford came back at their home ground. With the aggregate score at 2-2 deep into injury time, Leicester were awarded a penalty for very soft foul/dive from Antony Knockaert and that's when things took a turn for the unbelievable.

The Foxes' advancement was virtually a sure thing as Knockaert just had to convert the penalty to seal the win, but former Arsenal keeper Manuel Almunia changed all that by making the save and then also saving his follow-up attempt. As the home fans celebrated, the ball was cleared up the pitch and Watford instantly composed themselves to mount a counter attack. A cross was played in to Jonathan Hogg, who headed the ball towards the penalty spot, where Troy Deeney drove in the winning goal in the 97th minute.

Everyone lost their minds. Watford manager Gianfranco Zola got run over by a member of his own staff, but kept on celebrating. Leicester's players were understandably stunned and Sky Sports' commentator couldn't get his words straight. Here's his perfectly bewildered call...

Sir Alex Ferguson's final home match at Old Trafford played out in the most Alex Ferguson way possible. Starting with a unified guard of honor from the players and staff of both Man United and Swansea, a smiling Ferguson took his seat on the bench while the home fans all waved their plastic "Champions 2013" flags and Wayne Rooney watched in exile from the executive suite prison cell. Instead of immediately chomping a wad of gum to death, he seemed a bit more relaxed. But being two matches away from retirement and just 90 minutes away from lifting the Premier League trophy for the 13th time will do that.

Chicharito scored the match's first goal in the 39th minute to give Ferguson a familiar 1-0 lead. Swansea's Michu did his best to try and taint the day by equalizing shortly after halftime. In the end, that old Ferguson magic won out as Rio Ferdinand scored in the 87th minute — his first goal in five years — to give Man United a 2-1 victory.

Following Celtic's 4-0 win against St. Johntstone, they were awarded the trophy for making easy work of the Scottish Premier League. At one point, Celtic manager Neil Lennon took the trophy over to the stands, pulled his winner's medal off his neck and handed it to a young girl in the stands.

It was a move reminiscent of when Jose Mourinho chucked his Chelsea 2006 winner's medal into the stands at Stamford Bridge, but more of a tender moment than a display of swaggering brashness. Lennon, of course, already has a Scottish Premier League winner's medal from last season. Judging by the girl's reaction, she's going to give this year's medal a good home.
