They were lucky to win because I don't know what's wrong with Chelsea, they always seem to start games well. However, by the end of the match, they seem to be playing with the ball anyway and start creating goals that aren't necessary. Take a look at the unnecessary foul that Gallagher committed in the final seconds of the first half, which resulted in a red card. they were just lucky to win, their midfield and defence are always at their best, but they still need to focus on that striker.
When Gallagher received the first yellow card i was just so sure he would receive a second yellow if he was not substituted because of his aggressiveness, I was just praying for the first half whistle to be blown so he can be replaced because i knew he would cost the team and receive a second yellow.
Chelsea did well to manage and win despite playing with 10 men, i never expected them to be able to hold Brighton till the final minutes. You can say they were lucky but a win is a win no matter how terrible they played. You can’t expect a 10 men team to play a satisfying football and I wouldn’t say they were playing with the ball, they were under pressure and they wanted to just hold on the lead that’s why they were defensive minded.
