Paris Saint-Germain boss Carlo Ancelotti said he is at a loss to explain his side's inconsistency, after their 3-0 win over Nice.
The Ligue 1 leaders slumped to a penalties defeat in the Coupe de France against minnows Evian TG but bounced back in style - with goals from Jeremy Menez, Zlatan Ibrahimovic and Clement Chantome ensuring a handsome victory at Parc des Princes on Sunday.
"We saw a lot of intensity and aggression. It was tough tonight," Ancelotti told Canal+.
"The key was there. I don't know why the team can play as well as they did tonight and as badly as they did against Evian.
"Anyway, it happened. We are happy with how we did tonight."
PSG goalkeeper Salvatore Sirigu said his side are not invincible, despite the talent within les Parisiens' squad.
"We're not untouchable," he added.
"We showed a good attitude tonight. We wanted to show that Evian was just a blip. We wnated to bounce back, we did it well.
"We don't pick our matches. We don't always do as well as we want in terms of playing well or playing badly."
Central defender Mamadou Sakho warned the title was not a foregone conclusion.
"Nothing is impossible in football. Mathematically it is not over and we still need to keep picking up points," Sakho said.
"It will be difficult for another team to take the trophy from us now though because we have experienced players able to deal with this kind of situation.
"I think the squad is strong enough and we have the right mentality to succeed and win this Ligue 1 trophy. That has been the goal all season and we can achieve that."
Star striker Zlatan Ibrahimovic agreed.
"It was good, when you win there is always a great feeling and we are almost at the title," the Swede said.
"We are not there yet though, we are still missing a little bit but it feels fantastic. After everything you have sacrificed and the work you have put in to win this trophy, I came here to win and we are almost there so it feels very good."
PSG hold a nine-point lead as they chase a first Ligue 1 title in almost two decades.
