Chelsea manager Jose Mourinho believes the atmosphere at Stamford Bridge is normally "not very strong".
The Portuguese coach, who returned to west London in the summer, was speaking after the Blues snatched a controversial stoppage-time equaliser against West Bromwich Albion on Saturday.
Eden Hazard converted a last-gasp penalty after Ramires appeared to dive to win the spot-kick - and Mourinho feels the fans responded positively when the team were pilling on the pressure in the closing stages of the match.
“This is Stamford Bridge's nature,” Mourinho was quoted as saying by Get West London. “We know that our fans are in love with the club, more than in any other club or the same, but it is a different profile.
“We know Stamford Bridge is not a very hot atmosphere, not a very strong atmosphere normally, and we accept that.
“But in the last part of the game, when they felt the players were up to have a go and a fight, they were very much behind the team and they support the team.”
Rather than disagree with Mourinho's comments, the chairman of the Chelsea Supporters Trust was in agreement with the club's manager.
“We, as a Trust, have had dialogue with the club and atmosphere came up," Tim Rolls commented. "The atmosphere isn't all it could be and that's been represented to the club by both us and the Fans Forum (on which the Trust is represented).
“There are a number of contributory factors: the lack of young people, who are more inclined to sing; the lack of standing in the ground; and the cost of getting a ticket are all part of it.
“We need to get more people in to Stamford Bridge who want to sing. And, from my point of view, that means more younger people.”
Saturday's dramatic 2-2 draw against West Brom means Mourinho's undefeated Premier League record at Stamford Bridge remains intact.
