Chelsea are expected to compete in the top 6 this season, but Pochettino has a chance to compete in the top 4 if he manages to find a solution to his team's performance problems. Many Chelsea players still lack confidence in a match, so of course that makes the team fail to perform well.
Chelsea's performance in the Premier League will be put to the test once more when they host Luton on Friday. The only times the two sides have faced off was in the FA Cup, which Chelsea won both times and not in the premier league. This is the first time Luton is appearing in the premier league, and they are playing against the Chelsea team that has won them in their FA Cup meeting twice(2021 and 2022).
The outcome of tomorrow's game will tell me whether Pochettino is ready to take Chelsea to the top spot. Chelsea can't afford to lose another 3 points to a team that is new to the premier league.
I agree that they have to win, still Chelsea has to win and that is a heavy load to bear, particularly when they are not particularly on a hot streak.
Luton town will play with much less at stake, for them a draw is a great result and a loss is not particularly bad.
