The 47-year-old, who famously won the World Cup with France in 1998, commented that he thought Chelsea fans had become greedy due to their recent success and pointed to their Premier League rivals as an example of how to make an atmosphere.
“The fans have become, as they say in English, ‘greedy’,'' explained Leboeuf. ''In other words they’ve won everything so they’re happy. When I arrived there, they hadn’t won anything for 25 or 26 years so they were boiling hot.
“No, for the great atmospheres you need to go to Newcastle, Liverpool, who are desperate to win things. Chelsea is calm.”
Earlier in the season, Jose Mourinho infamously accused the Chelsea supporters of being too quiet and likened playing at Stamford Bridge to playing in a empty stadium.
“Everyone knows how much I feel connected to this club and the fans,” Mourinho was quoted as saying in the Telegraph. “At this moment it’s difficult for us to play at home though, because playing here is like playing in an empty stadium.
“The team then starts playing like it’s a quiet, soft game at home. It’s difficult to get that strong start where the players, team and fans at Stamford Bridge [are all together].
“I was today looking around and it was empty, but not in terms of people because it was obviously full. That’s what frustrating.”
Are Chelsea supporters really that quiet?
Away from home, it could be argued that Chelsea fans have one of the loudest followings. However, at home, like most teams, it's quite underwhelming.
Although the Blues may not be the worst offenders for silence in the Premier League, their current standing in the league table leaves them open for criticism when they are not constantly right behind their team and playing their own part in their title push.
While many Chelsea supporters will want the crowd to be regularly louder at Stamford Bridge, the key will be ensuring the big occasions at home do have a fantastic vocal support.
The Champions League clash against Paris Saint-Germain on Wednesday will perhaps give a better reflection of the supporters' passion and show whether or not they are deserving of the criticism thrown their way.
