Chelsea won this match. But I would not say that their performance was very good. Their performance was perfect. Chelsea managed to score four goals without attacking too much. Chelsea's every attack was excellent. Chelsea is slowly improving it's true. But they have to play better if they want to fight for the title. Brighton attacked a lot in this match. Chelsea players made a total of 8 shots in this match. On the other hand, Brighton players made 16 shots. But I will say Pochettino's start is not bad. With the help of Poch, Chelsea's performance will be better next season.
Although in the end Chelsea's four goals had to be paid for by goalkeeper Kepa who also concede three goals, right
Because I missed this match that's why I was curious about the four goals as you said and it seems you forget to explain the final score of the match, but after know the final score it turned out to be a narrow 4-3 win for Chelsea
Nothing special in my opinion because in the end Brighton also managed to score a goal in this match
