I think Chelsea was really lucky to win the game because it wasn't expected that they will be able to win the game based on how they have been performing. I was expecting the game to end in draws but Fulham didn't play well like the way I expected. If Fulham team had performed well I don't think it will be easy for Chelsea to win the game . Chelsea still have hope to meet up top four position if they can start performing better in their games.
It looks like luck because they only won by a narrow score and the goal was scored via a penalty kick after a Fulham player fouled one of Chelsea's players, but actually Chelsea continued to appear to put pressure on the away team but unfortunately, their chances were not able to penetrate Fulham's defense, even their opponents several times made quite good attacks and threatening their goal.
Chelsea was quite grateful because Cole Palmer managed to calmly execute the penalty kick because if he had failed, Chelsea would have gotten another bad result. In the final minutes, they managed to maintain their defense which continued to receive attacks from Fulham who were trying to get 1 point by doing so to equalize the score.
Chelsea's performance was ordinary even though this was their third win in a row and with a performance like that they would still probably lose to any team because their game development was not very good.
