Pep Guardiola believes Manchester City were a different side in the second-half of their 1-0 victory over Chelsea at Stamford Bridge on Thursday night.

Guardiola also praised 18 year old Manchester City right-back Rico Lewis for changing the game against Chelsea.

With the game goalless at half-time, Guardiola made a double change during the break with Lewis and Manuel Akanji replacing Joao Cancelo and Kyle Walker.

“All the managers try to make decisions to help the team – sometimes you are losing but the team is playing good and why I should change when I have the feeling they are doing well?” Guardiola said.

“Today, after 20 minutes, because you have to give them a little bit of time to try, I decided I didn’t like what I was seeing. So why wait?

“So I spoke with Rodolfo and Enzo, and we said: ‘okay, we have to change something otherwise it would have been more difficult.

“Everyone could see from the first minute of the second half, it was a different Man City.

“And this dynamic from Rico helped everyone to have their freedom. He changed the game from minute one.”
