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..
The referee in charge of the Tottenham vs Chelsea match which saw Tottenham lose 1-4 at home was not Simon Hooper but Michael Oliver. Luckily they didn't blame Oliver for the red cards given to two Tottenham players. If Hooper had served as referee in this match like in Week 7 of the Premier League vs Liverpool, perhaps Romero's hard tackle which endangered Chelsea players would not have received a red card.
Chelsea won with a reasonable score because it was in accordance with the quality of the game given by the entire team, not because of the referee's help so that Chelsea could win or not because of a robbery. If VAR had not canceled Chelsea's two goals, a score above 4 could have happened.
