Chelsea secured the signings of Kepa Arrizabalaga and Mateo Kovacic just before the close of the transfer window, and Jorginho was also added last month.
Chelsea defender Cesar Azpilicueta admitted after the game that he has been impressed with the signings made by the club this summer.
“Our signings have been very good,” Azpilicueta told BBC’s Match of the Day.
“They are adapting very quickly to the team and being comfortable in the team, and we have a very good squad.”
“It’s true when we created chances we were clinical. The goal just before half-time was massive going into the second-half.
“It meant we could control the game and we could have scored more goals in the end. In the first-half every ball and every cross was dangerous for them.”
