It seems to me that Chelsea won quite naturally and predictably. Firstly, Chelsea is a strong team and their level of play is much higher than that of Tottenham. secondly, the preparation for the match in Chelsea is a level higher. and finally, let's not forget about the fans. Chelsea fans create such an atmosphere that anyone will play at their best.
Yes, Tottenham had 9 players but that's no excuse. It's your own fault. Poor preparation and lack of experience..
It seems you watched from back of the TV and I have not seen many people applauding Chelsea in the match against Tottenham. From the start of the match, Chelsea had no directions neither good form, they were just running without directions. Chelsea started to perform well when the referee officials decided to destablize the Totenham team.
Chelsea is lucky although they had to win by whatever way, because the next few fixtures aren't friendly with them. They need to up their game and not rely on the controversial VAR officiating.
