Abidal was given a warm ovation before a friendly against PSG in Paris - which Barca won after a penalty shoot-out - when he performed a symbolic kick-off.
"I am feeling good, better than three months ago, and I am following the course set out by the doctors," Abidal, who will be 33 in September, told Spanish TV.
"I have to take things slowly, the operation was quite difficult.
"I have started to do a little work in the gym and I feel good, now I will continue and let's see if before December I can play on Barca's pitch.
"That's the objective, if it happens later no problem, the goal is to return and it's a nice one for me."
