The Ligue 1 champions have played five times in the past 15 days and host Benfica in the Champions League before travelling to Marseille this week to cap a busy period in the calendar.
However, Ibrahimovic believes that PSG prepare sufficiently enough in order to maximise their chances of winning each game.
"We have many games, every three days," Ibrahimovic told the press. "It's a game which is normal and to be 100% for every game is not easy.
"We prepare very good, we keep the balance from training and the games and that's why we make a lot of changes so we get to rest many players and the players that don't play a lot play as well.
"We have a big team, many players and when we do this rotation with many players I think we are ready for the Champions League, so in three or four days it's another game."
PSG beat Toulouse 2-0 at Parc des Princes on Saturday.
