Verratti has been sidelined since February with a groin problem and he is now back in full training with Laurent Blanc's squad, but the coach is unsure how much to push him at present.
Blanc has a full Paris Saint-Germain squad to choose from for the showpiece clash against Lille, but has urged patience from his returning star.
He told reporters, "His injury is delicate, it takes patience,
"It has taken time and hard work on the part of the player and the staff.
"Marco is training normally, I am happy for him. I cannot say more. Hopefully he will be in the group tomorrow [Saturday].
"For the first time in years, the whole group is training. For a long time this has not happened. It's good news."
