The former Manchester United star, does not like life on the bench in Spain, and is refusing to sign a new contract with the club.
The Madridistas are prepared to let Beckham go for a cut-price £5 million, and will take a £20m loss on the player, instead of waiting until his contract ends next summer.
A club source told The Sun: “Beckham has made his feelings clear over the past few days.
“If the coach continues to leave him out of the team then there is every chance we will accept a suitable offer for him in January.”
Becks was signed from Manchester United for £25 million, in July 2003.
