The French capital outfit left it late but Neymar and Edinson Cavani goals were the difference at Parc des Princes.

Speaking after the final whistle, Emery declared himself satisfied that ultimately the hosts' quality shone through.

"We were up against a side that defended very well," Emery said. "They caused us plenty of problems.

"It was a good challenge for us -- we are always looking to improve. Winning matches easily can sometimes lead to false sense of security.

"Today we were tactically smart. We showed patience. We started well but just could not find that final ball. We had to answer the challenge and we did that in the end."

Cavani's goal means that he now has 17 from the first 15 matches in Le Championnat this season, the first time that has been done since Olympique de Marseille's Josip Skoblar back in 1970-71.

The Uruguay international acknowledged Troyes' disciplined and organised display but felt a rotated PSG side still merited all three points.

"The most important thing was to win this match," Cavani said. "We have extended our lead at the top of the table.

"It was a very tough game because Troyes were tactically perfect. It is a great win for us that will help us improve.

"The entire squad is ready to do their bit for the team but it is also normal that certain players lack a bit of rhythm when you are not playing regularly."

Goalkeeper Kevin Trapp was one of those fringe players lacking a bit of match fitness, but he still kept a clean sheet and made a few impressive saves in the process.

"I was very happy to be back on the pitch but the most important thing was that the team won," the Germany international said. "It was a very difficult match.

"Troyes defended very deep and very well. It was not easy to find a way through but in the end, our attacking quality won the day.

"It is an important result. Now we have a 10-point lead over Marseille in second place."

Giovani Lo Celso also got a chance to impress in midfield and although the combination of him, Marco Verratti and Javier Pastore did not work that well, the Argentina international was thankful for his chance.

"It was a really hard-fought win over a side that afforded us very little space," Lo Celso said. "They had some very quick players in attack so we had to be careful.

"We did not manage to score early and the longer it went on, the harder it got. We opened the scoring with a beautiful goal.

"The most important thing is that the team won. I am one of the players knocking on the door for a starting role. I was lucky enough to play tonight and I tried to give my best for the team."

Next up for PSG is a trip to Strasbourg, where Emery is expected to rotate his squad again before Bayern Munich in the UEFA Champions League next week.
