The Italian tactician was left slightly disappointed as his side were held to a draw away at the Velodrome in a match that he believes his title challengers lacked intensity
The Italian's star-studded squad drew 2-2 against the current Ligue 1 leaders. Andre Pierre Gignac scored his second to level the tie after a quick double from Zlatan Ibrahimovic had put the visitors ahead.
The result left Ancelotti disappointed who stated that his players lacked intensity in their play due to their game last Wednesday night in the Champions League.
"We have not played with great intensity, I grant you. We could have put more intensity, but we left a lot of energy in Wednesday's game and the trip to Portugal," Ancelotti told reporters after the match.
"We did not have a great game, it's true. We should have exercised better control and should have tried to score again after taking the lead."
Nevertheless, the former Milan boss does not believe the result was disastrous and even admitted he felt his side could have still come away with all three points.
"This is not a bad result. We even could have won. We took the lead but we were not able to control the game then. It's a shame because we could win. We gave a good performance with a good grasp of the game and a good state of mind," he continued.
PSG's Italian starlet, Marco Verratti, has been impressive since his move to the French capital, however, found the going tough against Marseille.
He added: "Verratti? It was not a good match for him. But, this is normal, he is trying to learn with us. But he remains a very good player and a very important one for us."
