Chelsea performance was poor as how can they allow Aston villa to come from behind when they scored very early in the match, Chelsea goal came in the 9th minute and they got chances to score more goals so they can kill the game but they allow Aston villa to come back into the game and then they used that momentum to score another goal and won the game. Aston villa aren't a club you'll allow to equalized you as they're known for coming back this season to win games. Among clubs that have been able to achieve that this season they're in the first position as seen in the image I shared. Aston villa deserved to win this game and Rashford was the reason for their win.
