Paris Saint-Germain manager Laurent Blanc believes his side can improve after drawing their first two Ligue 1 games of the season.
The reigning champions could only manage a 1-1 draw in their opening game at Montpellier, before then recording the same scoreline at home to Ajaccio.
Blanc’s side had 39 attempts on goal during last Sunday’s game at the Parc Des Princes, but only gained a point thanks to new signing Edinson Cavani’s late strike.
However, the former Bordeaux boss is not worried and remains confident PSG will improve.
“We want to become more effective,” he said.
“Our preparation is not over and I think if we were 100 per cent against Ajaccio (we) would have won.
“We thought (about) a lot of tactics. I do not want to be locked into a system, it must be able to change to adapt to situations.
“Above all, there is always the desire to find balance.”
Blanc also explained he has no imminent plans to make further signings after the additions of Cavani, Marquinhos and Lucas Digne in the close-season, but admitted he may delve back into the transfer market if they sell some players.
“If this happens and we still have time, then we may think,” he added.
“Today, there is no news.”
Blaise Matuidi could make a surprise return to the PSG side for their trip to Nantes on Sunday.
The French midfielder has recovered well after suffering a head injury in the stalemate against Ajaccio.
