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.
Agree with what you said, Chelsea is only lacking in final solutions, and now Pochettino is even more confused because Nicolas Jackson cannot be included in the XI because he has accumulated cards. It is possible that the match against Fulham will be played without a pure striker, unless Pochettino uses Armando Broja. If a total of nine players cannot enter the XI this time, it is dominated by 7 players injured and 2 players banned from playing.
With this situation, it is difficult for Chelsea to get full points when they meet Fulham, especially since Fulham will act as hosts. Although I hope Pochettino can bring the Blues to victory in this match, at least 3 points will relieve him of the pressure a little.
