Chelsea fans were disappointed with what they saw from the Chelsea team in the first-half of the Conference League clash against Servette.
The first-half ended in goalless draw, but the performance from the team was poor.
Chelsea fans booed as the referee blew his whistle for half-time.
Reacting to being booed by Chelsea fans, Chelsea boss Enzo Maresca said: “The message is quite clear: We are in a moment where we are learning how to manage the game.
“Probably in some moments, the right thing was to do exactly the same thing but on the other side.
“The intention to keep the ball is the correct one, especially when you are 2-0 up. So the intention is good but probably where is not good. We tried to manage the ball in the last 10 or 15 minutes on our side but we need to try to do exactly the same on the opposite side.
“I can understand but the important thing is to win the game. Clean sheet, we did nine changes, we had players like Renato [Veiga], Axel [Disasi], Pedro [Neto] and even Marc [Guiu], Filip [Jorgensen], it was his first official game, so many good things.”
