Eric Abidal insists his health will be the key factor in whether he signs a new contract at Barcelona.

The 31-year-old left-back helped the Catalan club win the UEFA Champions League last season after recovering from surgery to remove a liver tumour.

The France international, who moved to the Camp Nou from Lyon in 2007, is under contract until the end of the season.

"Barcelona is the best club in the world and I want to finish my career here, but I would not fool anyone and the first thing is my health," he told Marca.
