The world learnt a few things on Sunday; it learnt that Chelsea are Premier League champions, it learnt that Palace are no pushovers and it also learnt that Jose Mourinho is an Eagle.
Well, sort of.
The Chelsea boss turned to face the Palace fans in the away end at Stamford Bridge at halftime and gave them big thumbs up. They had, of course, been singing their hearts out for 45 minutes. He then turned to the home fans behind the dugout and shook his head before simulating sleep.
