Les Parisiens' boss believes that his side must concentrate on getting out of their Champions League group, before setting any higher expectations for their European campaign
Dinamo sit bottom of Group A after failing to pick up a point from their opening two fixtures, but Ancelotti believes that every match requires focus to achieve victory.
"To win a Champions League match, you must put in intensity and concentration. This is an important game, such as returning to Parc des Princes. Both confrontations will be crucial I think," explained Ancelotti, speaking to reporters.
"We must first get out of this group and then see what we can do. I hope we can go as far as possible. But the pressure is constant and necessary. There are six games in this group, on Wednesday it will be the third, everything remains to be done.
"I just hope that Pastore will have a great game, find all his confidence and demonstrate his capabilities."
Blaise Matuidi shared the same sentiments as his coach, as the 25-year-old spoke of the commitment and effort required to bounce back from their defeat at the hands of Porto.
"We are focused on our game, without thinking about our opponent. We come here to win. I feel good about this team, the players have helped me a lot in my progression," he said, speaking to reporters.
"For each match, I want to give 120 per cent, I always have this motivation because no game is easy. I do not have the talent of some players and I have to compensate for this with maximum commitment.
"We learned from our defeat in Porto and I hope we will win again in the Champions League," he said.
