Nothing is impossible, Chelsea can put up a good performance, while Liverpool and others begin to lose points.
Even if Chelsea starts performing better now, it won't still lead them to winning the Premier League title because if Liverpool begins to lose points, Arsenal and Nottingham Forest who are third and second in the league table won't lose points as well which means any one of them will stand a better chance than Chelsea. Where Chelsea can stand a chance of winning a trophy is in the Conference League where they are doing more better but in the Premier League the highest they can achieve is coming out in the top four positions and qualify for the Champions League next season. However, we should not even exaggerate a possibility for Liverpool to lose out in the top position because the Premier League title is all they are left with and they will do anything within their power to protect it till the end of the season.
The position where Chelsea is currently is in the premier league stand, their is no guarantee thst Chelsea will surely secure the fourth position because their are teams under Chelsea that their points are even close to Chelsea, so any mistake from Chelsea these clubs can take over the fourth position. Chelsea has a lot of job to do to win every of their games till the end of the season.
As for the first position and second position, it has been secured already by Liverpool and arsenal, no team can get to this point in this season . I think where the competition is now , the third position and the fourth position.
It's impossible for Chelsea to win the rest of their matches. No one knows if Palmer is back from injury because without him, Chelsea will find it difficult to win most of their upcoming matches, and that will make it difficult for them to finish on the fourth position. Only, if the clubs behind them follow their footstep in the outcome of their own matches which is not possible.
