Chelsea boss Jose Mourinho insists his players will not get complacent despite their recent run of good form.
The Blues have a six-point lead at the top of the English Premier League and already safely through to the next stage of the Champions League.
But the Portuguese says there is no room for complacency in his team.
"No. That's the only risk we don't have," Mourinho said.
"We have all the others that belong to football: a bad period, injuries, unlucky matches, other teams growing up and becoming stronger. Complacency is not a risk we have because it's not in the profile of this group.
"We were winning 5-0 against Schalke [in mid-week] and in the 88th minute, Hazard made a sprint to defend.
"They have changed. There is a clear evolution with these people. As a group they can't be complacent.
"I'm sure there is much more to come [from this team]. It's a young team, with lots of young players.
"I have two more years of contract to work with them, they want to stay, I want to stay. There is a lot ahead of us but this team has all the conditions to be better.
"But all the factors I said that can effect us negatively, except complacency, are part of the game.
"To be fair my untouchables now are the ones that are not playing. They're responsible for a lot of what we are doing.
"I don't have one single player from the ones that are not playing, from the ones that doesn't feel like a first choice, that is not training very hard, that is not behaving very well, that is not part of the group, not ready to help playing 10 minutes or one minute, staying on the bench or even going into the stands.
"Life is easy when you're always playing and winning, feeling high in your esteem. Life is difficult when you're not playing because a player is born to play. All these guys in my squad are absolutely fantastic and I'm so happy with them."
