There were boos from the fans after the final whistle following Chelsea’s 1-1 draw with West Ham at Stamford Bridge on Sunday.
Chelsea boss Antonio Conte admitted after the game that it is normal for fans to be disappointed.
Asked about fans booing Chelsea’s performance, Conte said: “For sure there is disappointment and this is normal. Because we must be disappointed.
“We are paying a lot for this situation and if it happens a lot then you have problems.
“We must be frustrated for this game and the final result. This describes our season, this game describes it very well.
“Many games where you have a good performance and have chances but are not clinical. How many times have I said to you? A lot of times.
“One chance for them and they score. This describes it very well. We are talking about improving but now another not positive result as we drew. You have to win this game.
“I hope my players are frustrated, because that is the right mentality.”
