Chelsea's chances of winning will indeed be greater, but we know how the Chelsea squad's performance currently tends to be unstable. Pochettino must be very aware of his team's current performance. he is still having difficulty changing Chelsea for the better. he may need time, or perhaps until fans' patience will run out when no change is shown.
but I think the result could be bad for Chelsea, or the best possibility is a draw.
If you look at all of the matches that Chelsea has played that many expected them to win, you will note that they are always the ones with the best performance and always dominate the game, but luck is not always on their side to win. They don't know how to create those opportunities, and the few that do create are never used to their advantage to score a goal. I won't say they have a horrible striker, but he needs to improve his finishing to give his club an advantage over other teams in the competition.
The forthcoming encounter against Fulham might be similar, but following their last game against Brighton, in which they scored two goals but one was later disallowed, I will give them some hope that they will be able to win this match. It will not be nice if they do not win; a draw is not even an option for them; if they draw, we may deduce that their form is inconsistent, which will not help them.
