Ibrahimovic has seven goals in his first five Ligue 1 matches, and Nene believes that the Swedish striker has given the whole squad a lift with his early performances.
Nene told RMC Sport: "He impresses me in training and in matches. He really is a wonderful player, who will help us a lot. We are very happy that he is here."
PSG continue their title charge with a home match against Sochaux on Saturday, September 29.
