Kylian Mbappe scored and came through unscathed along with fellow Paris Saint-Germain stars Lionel Messi and Neymar in their final match before the World Cup, a 5-0 Ligue 1 rout of Auxerre on Sunday.
PSG coach Christophe Galtier opted not to rest the attacking trio against the Burgundy side as the French champions sought to extend their lead at the top of the table before the break for the tournament in Qatar.
"None of my players had sent me a signal of fear," said Galtier.
"My obsession was that my team could express themselves as freely as possible without the psychosis of an injury.
"The players responded present, were serious, focussed.
"It would have been a great sadness for me if one of my players were injured before the World Cup and I quickly made the changes to spare each of them."
Mbappe scored the opener after 11 minutes in Paris for his 12th league goal this season after good work by Messi and two other World Cup bound players Moroccan Achraf Hakimi and Portuguese Nuno Mendes.
Spain's Carlos Soler nodded in the second after 51 minutes and then set up Hakimi for the third six minutes later. Two players who are not going to Qatar, Renato Sanches and Hugo Ekitike came off the bench and added goals in the final ten minutes.
The Parisians moved five points ahead of Lens, who won 2-1 at home against Clermont on Saturday, with Rennes a further five points adrift in third.
Galtier added: "We are first and undefeated, we worked on different systems and it took us time to find the better solution so that my fantastic trio can express themselves and find the best balance.
"There are still many lines of work. The only small regret I have is not having beaten Benfica in the Champions League."
PSG drew twice with the Benfica in their Champions League group and qualified second behind the Portuguese club.
For their final match before the World Cup, the MNM trio -- Messi, Neymar, Mbappe -- did not really sparkle in a game played without great intensity.
That did not prevent the champions giving a demonstration of their goal-scoring prowess before a break until their next Ligue 1 match on December 28 against Strasbourg.
