Ex-Barcelona defender Eric Abidal has revealed former team-mate Dani Alves offered him part of his liver when the Frenchman needed a transplant.
Abidal, 34, who now plays for Monaco, was diagnosed with a liver tumour and underwent an operation in March 2011.
He had a transplant in April 2012 with part of an organ donated by his cousin.
"When I had to undergo surgery, Dani wanted to donate his liver," said Abidal in an interview with Spanish radio station Catalunya.
"Logically, he couldn't because he is a professional footballer."
Abidal made a playing comeback in April 2013 after his liver transplant, but was released by Spanish champions Barcelona in the summer.
Brazil right-back Alves, who was Abidal's team-mate at the Nou Camp for five seasons, decided to wear the France international's old number 22 shirt following his return to Monaco.
Abidal added: "The story with Dani goes beyond the jersey. He knows it. Me too. We are friends and we talk about everything. He wanted to support me.
"And besides, he's a very good person. He was my neighbour and his ex-wife and my wife are friends."
Abidal also tweeted: "Thanks brother" alongside a picture of himself and Alves playing for Barcelona.
