Luis Enrique also spoke about the test facing his team when they take on Leverkusen in Germany.
"It's difficult to give Leverkusen credit for signing 20 players and a new coach. They score goals and they can defend very deep, they know how to put pressure on. They can do anything and we'll have to manage it properly. Every match presents different situations, we'll see after training what condition our players are in," he told a pre-match press conference.
"We've brought in a lot of young players who have shown they have quality. This start to the season has been different and very difficult because we've overcome difficulties we shouldn't have had to overcome. We've shown resilience. Tomorrow is a very important match because the sooner we take points, the better. We don't want to think about it, but we want to try to win this match."
Meanwhile, Leverkusen boss Kasper Hjulmand says his team will be facing the best in the world when they come up against PSG.
"PSG are perhaps the best team in the world. They have won five trophies in this calendar year. We have a lot of respect and it will be a difficult task. But we're also looking forward to it, because Champions League matches are always great. We're at home and are determined to show our qualities. We'll give everything to win," he said.
