I think Chelsea are still in a better position compare to Tottenham, the match have already started, and we may know who is going to win the match after the first half of the match, base on their performance, let’s no rush things.
During the first half, Chelsea were still unable to score a goal with various attempts that they continued to try. Only in the second half the awaited goal came through Enzo when the match had been going on for 5 minutes.
I agree with you that Chelsea are still in a better position than Tottenham because Tottenham continue to experience a decline in performance even though they performed well at the beginning of the season.
Winning for a while does not guarantee that Chelsea can survive until the end, but from Chelsea's efforts, I think they can maintain this advantage.
