Despite dominating French football since the arrival of the Qatar Investment Authority in 2011, PSG have yet to see that success pass over to Europe's biggest club competition.
But after disposing of German duo Borussia Dortmund and RB Leipzig as well as Atalanta in the knockout stages to date, Thomas Tuchel's charges now face Bayern Munich in Sunday's decider with the chance to make history.
Verratti has been at Parc des Princes since moving from Pescara at just 19, and he admits that the final is the biggest game of his career to date.
"The Champions League is always difficult. So far, we've had an incredible journey," the Italy midfielder explained to reporters in Thursday's press conference.
"We have 90 minutes left, these are the most important 90 minutes of our lives as a footballer and of the history of the club. You have to be prepared.
Verratti missed out on PSG's quarter-final clash against Atalanta due to a calf injury, but made an appearance off the bench for the final eight minutes of their last-four win and insists that he is nearing a full recovery and hopes to feature on Sunday.
"I'm better, I started again slowly with the team. This injury was a bit hard to digest," he added.
"I have resumed with the group for 2-3 days and I will do everything to play the match. I was available in the semi-final. It is the coach who will make his decision."
In his absence former Manchester United star Ander Herrera has come to the fore in the engine room, and Verratti could not be more delighted for his team-mate.
"For us, this is no surprise. We already knew Ander. He's a very important player," he explained.
"This season he has had injuries that have kept him from being available on several occasions, but he still gives 100%. He made two incredible matches. We are very happy with what he does, but we do not just finding out about him here.
"He's 31, he's already won the Europa League with Man Utd, he's won the Premier League too. He has shown his many qualities here."
