We must know before this match takes place, not many make them as favorites, and even some are very confident saying Arsenal will win. But all that can be answered, especially after they can lead 2 goals in the first half. Entering the second half, Arsenal began to realize that this was not the Chelsea they had seen, and were lucky enough when they could equalize to make the match end with a draw.
The reason the game finished in a draw was due to Chelsea's goalkeeper. Chelsea's team got off to a strong start in the first and second halves, but a minor error by Chelsea's goalkeeper led Arsenal to score their first goal at 77 minutes of play. That goal by Rice inspired Arsenal to think about mounting a stunning comeback against Chelsea, which they did, leading to a draw at the conclusion of the match.
The Chelsea team looks good in the 4-4-2 formation. How I wish Pochettino would stick to the formation. They really maintain and play well in such formation against Arsenal but the substitution of Palmer and Mudryk changed the ball formation of the match in favor of Arsenal
