The Daily Mail says Bale is on the verge of signing another multi-million pound contract less than three weeks after he became the world's most expensive footballer.
Adidas, with whom Bale has been associated since he was 16, are hopeful that the £86million Real Madrid star will agree a long-term extension to his boot deal and personal sponsorship.
Bale's six-figure agreement has surprisingly been allowed to run down into its final year.
An adidas source said: "We are confident that we can keep Gareth, who has always been very loyal to the brand. But the deal has to be right for both of us. It helps that we have the experience of handling David Beckham when he was at Real Madrid."
