It doesn't matter how good a team is. It is almost impossible for any team to win under such circumstances. That's what happened here with Tottenham.
The big mistake was when Spurs decided to focus on attacking, pushing all their defenders forward to the halfway line. The lack of these players did create a dilemma for Spurs, and in the second half, during injury time, chelsea really capitalized on this by delivering a pass to their striker. There's no denying it... Chelsea's performance was truly captivating and exceeded most people's expectations.
it seems that Chelsea is indeed very good at facing big teams like Arsenal, Man City, and Spurs, rather than going up against underdog teams, where Chelsea appears to face a bit of difficulty when dealing with teams in the mid to lower rankings in EPL.
They had no mistake, they already lost two players to red card so they had to risk it. They attacked Chelsea even with the red card and that was quite brave to see.
Pochetino and Chelsea would have looked stupid to me if they had not won that game.
Chelsea also tried to break Tottenham Hotspur but all those attempts failed as they were all ruled off to be offside.
I will agree with that, they have a good mentality against big clubs. Like they've done with Arsenal. Spurs just happened to be unlucky else Chelsea wouldn't have won. Against smaller clubs, Chelsea underestimate them and end up losing woefully. Let's take for example Brentford, they should have won that game but how did they lose? Crazzzzzzyyy!
