The City boss was asked if he had decided on his starting XI for Saturday's final.
He indicated he hadn't made a final decision as yet, but that whoever plays doesn't matter, because he trusts the squad completely.
"They are ready," said Pep.
"I know how good they are - all of them. I will not change because of one or two sessions.
"I have known most for many many years. The starting XI is not done, not yet."
The Catalan also admitted his players had exceeded expectations this campaign and in reaching the final, they are ahead of schedule.
"I never thought this was the season to get to the final," he said.
"I never started this competition like that even at Barcelona. We are a similar team to the previous season when we were out.
"The margins are so small and have not changed much. Now we are quite satisfied to get to the final but we know if you don't have a huge desire to win it, we know it won't be possible to win the game and win the Champions League."
