Chelsea were beaten 1-0 by Everton this weekend, with Gylfi Sigurdsson scoring the game’s only goal from the penalty spot, and former Blues centre-back Leboeuf felt there was a lack of bite in their ranks at Goodison Park.
Had they won, Chelsea would have sat top of the Premier League – with Tottenham Hotspur and Liverpool dropping points this weekend – but instead they slipped to fifth.
Leboeuf was concerned by the manner of the loss and senses there aren’t enough ‘warriors’ who are willing to fight for a win.
And he suspects that could prove costly if they don’t learn how to ‘steal’ results in a gritty fashion when they’re not playing at their best.
‘It’s what happened yesterday [Saturday]. You have to be a warrior, you have to sometimes be dirty and half of the team is not capable of doing that.
‘The team is young, they have maybe no experience and you have to find a way to win.
‘Chelsea tries to play too nice football, nice in the middle of the park but not effective yesterday [Saturday], especially up front and at the back.’
