The French giants are looking to become the first side to win successive Champions League titles since Real Madrid in 2018.
An exciting game is expected at the Puskas Arena in Budapest, and initially, PSG feared they would be without Ballon d'Or-winning forward Ousmane Dembele.
He was substituted with a calf strain suffered during the first half of PSG's clash against Paris FC on May 17, and then missed training in the following days.
However, in a huge boost to Luis Enrique's side, the 29-year-old has confirmed he will be fit for the final next weekend.
"I feel much better than on Sunday," Dembele told French broadcaster M6. "I had a little scare, but the doctor told me there was nothing to worry about. I felt a slight discomfort and I preferred not to take any risks. I will be back on the pitch on May 30."
Dembele has 30 goal involvements in 39 matches across all competitions this term, and he will be eager to add to that total in the Champions League final.
