The second leg of the Bayern Munich v Porto Champions League quarter-final was a bizarre game of football.
Sure, Bayern responding to a first-leg defeat by scoring five goals in the first half made it pretty memorable - but there was a far more remarkable incident just off the pitch.

We figure there must be a reasonable explanation. So here a few theories:
He was laughing so hard at the ineptitude of the Porto defence that the seams of his trousers couldn't take the strain
His trousers were splitting their sides at the idea that he'd leave this Bayern side for Man City
He realised that being the best manager in the game and the most stylish was making everyone else feel bad - so deliberately displayed a flaw to make the rest of football's bosses feel less inadequate
He was making a point - he is so cool, talented and generally awesome, he can still look cool even with his trousers flapping in the wind
