Chelsea have now won three consecutive games after beating Leicester City on Saturday afternoon thanks to goals from Ben Chilwell, Kai Havertz and Mateo Kovacic.
With Chelsea leading 2-1 at half-time, Chelsea boss Graham Potter took off Joao Felix at half-time and brought on Conor Gallagher.
Explaining the Felix for Gallagher change, Potter said: “Tactically. I wanted to use an extra midfielder. I felt we needed someone who could win the ball, a different profile and I thought Conor was fantastic.”
