Eric Abidal has been offered a contract extension by Barcelona but will delay putting pen to paper until he has proved his fitness.
The French full-back's current deal is set to expire at the end of the 2011/12 campaign.
Barca are keen to keep him at Camp Nou for the foreseeable future and fresh terms are on the table.
Abidal is reluctant to sign, though, while his long-term health remains an issue.
The 32-year-old had surgery to remove a liver tumour in March, before making an emotional return to action at the end of the season as Barca lifted the UEFA Champions League crown.
A full pre-season has allowed him to work on his fitness and he is one of only four players to have played every minute of the club's four Primera Liga fixtures this term.
Abidal is, however, still undergoing regular medical tests and treatment and believes it would be wrong of him to sign a new contract until he knows precisely where he stands.
"I have an offer from the club," he said.
"I have discussed it with (sporting director Andoni) Zubizaretta but the first thing I said was that I don't want to deceive anyone.
"I want to get back to playing at my level. I know it will be tough because we are not machines.
"I will make this effort because I like this work and for my team-mates and the club."
Reports have suggested that ambitious Ligue 1 outfit Paris St Germain are keen to take Abidal back to his homeland, with their Qatari investors looking to assemble a world-class squad, but the defender insists there has been no formal approach from the French giants.
"Important people have arrived (at PSG) and it's possible they are interested but I have not had any offer," he said.
"The only offer is from Barca, although there are other teams interested."
