Chelsea got off to a winning start in the Premier League this season but it was one of their former players who was rated the man of the match on the BBC Sport website.
Left-back Tariq Lamptey left Chelsea for Brighton in January and he impressed against his former club, making more tackles and interceptions than any of his team-mates as well as excelling going forward.
"He's fun to watch, isn't he?" said Seagulls manager Graham Potter afterwards, who said the 19-year-old's approach is "refreshing".
Chelsea manager Frank Lampard said the Blues "tried to keep him" after he made it into the first-team squad, but could not convince the defender to stay.
"You have to give him a bit of credit because he wanted to play games. He'll be a great player here [at Brighton]," Lampard added.
Lamptey picked up the highest rating but how did Chelsea's debutants Timo Werner and Kai Havertz get on? Find out below.
