The beaten Champions League finalists lost 1-0 to Lens in their first match of the new league campaign, although manager Tuchel wasn't too annoyed with the result as a number of key players were missing - including Neymar and Kylian Mbappe - after contracting coronavirus.
He told Canal+: "I don't think we could have done anything better tonight. I was happy with the first half we had. We controlled the game completely, and we had possession.
"We struggled to create scoring chances today. No opportunities? Yes, I agree. But we have a small group, and we are missing the players who make the difference.
"With a young team, we made a decisive mistake and we couldn't take advantage of their mistakes. A draw is the best we could have hoped for."
Tuchel explained that he is keen to strengthen his squad for the season ahead, with a deal for Roma's Alessandro Florenzi lined up.
The German manager said: "I hope that will be resolved. I am very optimistic for him."
However, Tuchel denied that PSG will be signing Arsenal outcast Matteo Guendouzi.
When asked about a move for the midfielder, the 47-year-old coach said: "No, that will not happen."
