Chelsea suffered their third defeat of the 2017-18 season on Saturday, slumping to a shock 2-1 defeat to Crystal Palace at Selhurst Park.The reigning Premier League champions were facing a side that hasn’t scored a single league goal this season.Chelsea were strong favourites to secure all three points but found themselves a goal down after Cesar Azpilicueta turned the ball into his own net after 11 minutes. Tiemoue Bakayoko levelled the scores seven minutes later but Wilfried Zaha’s goal on the stroke of half-time proved enough to earn the hosts a shock victory.“Today was a difficult game for us,” Chelsea boss Antonio Conte said after full-time. “Our start was poor. We had to start with more personality.”Chelsea now find themselves nine points behind league-leaders Manchester City, who hammered Stoke City 7-2 this afternoon, in fourth place.“Despite this we have to find the will to fight,” Conte added. “This season we have to put 150% because it will be difficult.”

The tweet Chelsea posted before Palace match

Meanwhile, over on Twitter, Chelsea are being destroyed - and not just by Crystal Palace fans - for the tweet they posted about their opponents on Saturday morning.

The minute-and-a-half long video informed their fans that Palace have set a new record for the worst start to a Premier League season.

It then pointed out that Palace had failed to score a single goal in seven league matches, conceding 17 in the process.

To further emphasise Palace’s dreadful start, the video then displayed a graphic showing the scorelines from all of their defeats so far this season.

It then said that Palace’s last league goal was netted way back on May 14, against Hull City and scored by the former Chelsea player Patrick van Aanholt.

And so on, and so on.

This lad warned Chelsea

Interestingly, the first reply was from a Chelsea fan who tweeted: “Should really not show these stats..if it backfires it'll be embarassing..stop showing off.”

He saw the future.

Football fans destroy Chelsea's Twitter account

Chelsea are now being mercilessly mocked for the tweet and, let’s be honest, it serves them right.

It just goes to show that no matter how badly your opponents are playing, it’s never a smart move to underestimate them.
