The Barcelona boss says a decision has yet to be taken over a new deal for the Frenchman and says he would have no objections to the goalkeeper staying another year
The Frenchman returned to the first team recently after missing more than a year thanks to a liver transplant, while the goalkeeper made his intention to leave Camp Nou clear back in January.
"Abidal's renewal is a very special situation. We do not know yet how he will recover if there are games every three days," Vilanova said at a press conference. "For me, it wouldn't be a problem if Victor wants to continue another season. I didn't talk to him, but his decision was clear."
Vilanova has had his own battles with cancer and admitted that his relapse was a testing tame for Barca.
"It wasn't an easy situation for the club when I had my relapse. I would have accepted any decision they'd have made," he continued.
"I feel very good after the treatment. I didn't give a press conference earlier because there were still some side effects, particularly with my voice.
"I feel better every day. I feel strong enough and I'm very motivated to continue next season, if my health allows it."
Barca take on Athletic Bilbao at San Mames on Saturday.
