You are right and I agree with what you said because Tottenham could not win the game against Chelsea while they didn't have one player because of the red card but the 4-1reult was still not good for Tottenham and regardless of the game Tottenham had against Chelsea, they still lost another game agist Wolves with a 2-1 result while they didn't get the red card anymore and this is a good warning for this team to find their weakness and improve the team before they lose more points.
Definitely the red card was so much of an advantage for Chelsea and after the red card Chelsea's confidence became much stronger and they won as a result els I was Sure Tottenham was going to be really tough on Chelsea and it was possible they couldn't have won or even have such number of goals against Tottenham.
Tottenham is still a better this season as compared to Chelsea, that's my personal opinion tho. But it seem that loss impacted on Tottenham really negatively because since then their performance has really dropped and they have not been at their best like they have been since this season, they are suffering some injury tho but then they still have some key players like son and Madison who are very much strong, I feel they will do better by their next match.
