In a promotional event on Wednesday reported by Spanish newspaper AS, Gerar Pique spoke about Leo Messi's foot injury, which he suffered in their El Clasico win.
It has kept the four-time Ballon d'Or winner out of action while on international duty with Argentina, but the centre-back believes Messi will be fit to face Celta Vigo this coming weekend.
"I spoke with him, of course, and I'm an optimist. I believe he'll play in Balaidos, but everything depends on how he feels over the next several days. If he's alright, he'll play."
Pique then discussed his own form this season, after beginning in Luis Enrique's dog house to being hailed as the best defender in Spain.
"I feel great, confident, physically fit, quick...I feel like I'm helping the team and on an individual level, when things are going well, you feel better. But we need titles. We need to learn from what happened at the end of last season. We were at the same place as we are now and we all know how that ended. This all means nothing if we don't win titles."
Pique went on to discuss the possible summer departures of Dani Alves and Xavi, with both Barcelona legends set to move on from the Camp Nou and make their way to PSG and Al-Sadd, respectively.
"I'm not in a position to say anything, but with Alves' hard work and the great atmosphere he brings, I'd like for him to stay.
"A lot of the greatest players have passed through here. Pep, Puyol, Valdes, etc..and Barcelona lives on. Xavi means everything, his way is the way Barcelona plays, but the club will keep on breathing."
Pique was addressing the media after announcing that he would be donating €50,710 to the Relats Solidaris project to benefit the Institut Universitari de Neurorehabilitació Guttmann, who are the leading hospital in the medical treatment, surgery and full rehabilitation of patients with spinal cord injuries, acquired brain damage or any other neurological disabilities.
