Connor Gallagher’s two yellow card complicated things, but the Blues managed to see things through thanks in large part to Enzo Fernandez’s brace.
Chelsea made life difficult for themselves in a match that seemed straightforward as Brighton, who made several changes to the team after last Thursday’s Europa League match in Athens, put up a fight nonetheless.
The opening goal came from Enzo Fernandez with a header in the six yard box in the 17th minute. Moments later Colwill scored the second with another header.
Everything changed before the break as Buonanotte made it 2-1 and brought his team back into the match.
A good left-footed shot to the far post beat Robert Sanchez and shortly after Gallagher was shown a double yellow card.
But with Mudryk in fine form, everything was simpler and, despite being down to 10 men, the Ukrainian got behind the Brighton center-backs and won a clear penalty that Enzo Fernandez converted to score a brace.
However, Chelsea had to suffer and it could have been 3-3 if not for a standout performance from Robert Sanchez.
Joao Pedro cut the deficit in a 14-minute stoppage time and there was even a penalty in the 101st minute in favor of Brighton that was disallowed by the VAR.
There was a lot of tension at Stamford Bridge, but in the end Chelsea managed to hang on for three important points.
