Chelsea and Manchester City took their time getting out of first gear on Saturday, but Pep Guardiola's City side looked a cut above the Premier League champions.The home side lost star striker Alvaro Morata during the first half through injury and Antonio Conte decided to replace his leading man with a midfielder in the shape of Willian.That was a dead giveaway that the Italian did not believe his side could play City off the park and he was trying to stifle the unbeaten Citizens.However, City dominated proceedings and enjoyed all the territory on Saturday evening and deservedly emerged with the 1-0 victory.Kevin de Bruyne was the difference maker on the day and it's crazy to think sometimes that Chelsea actually sold him to Wolfsburg back in 2014.City would buy him one year later and in his six appearances against his former club, the Belgian international finally scored his first goal.Seeing as KDB is one of, if not the best midfielder in the Premier League right now, Chelsea fans were in meltdown on Twitter over his goal. Take a look at the best tweets below:

Just two weeks ago, Guardiola was raving about his playmaker so much so that he claimed De Bruyne to be one of the best players he's ever seen.

“Kevin is one of the best players I have ever seen in my life,” Guardiola said, “in terms of how he can make absolutely everything, everything. He is a top, top quality player. We are so proud and so happy he is with us.”

Despite a slight dip in form last season when City struggled for results, Guardiola doesn't expect the same this term.

“He’s a stable guy, so professional, he loves to play football, lives for that and is focused on that,” Guardiola said.

“Maybe last year he had a little bit up and down, maybe because we didn’t win too many games when we deserved to. But this season, since the beginning, in pre-season, not just in the States, and in Manchester, he is so stable.”
