The Welshman is still part of Andre Villas-Boas' squad, but with a move imminent the Liga giants has inadvertently made the player's would-be shirt available for purchase
Tottenham look set to sell the Welshman to the Spanish giants for a record-breaking fee, with confirmation widely expected in the coming days.
However, Real Madrid's official club shop website obviously missed the memo, and added '11 Bale' as a category in the 'shop by player' section, despite the forward still being part of Andre Villas-Boas' squad.
Madrid have previous in this department, with Luka Modric's name appearing on the club website before the £33 million move - again from Tottenham - was confirmed two years ago.
The inclusion of Bale's name was likely accidental, but it came on the eve of club legend Raul's return to the Santiago Bernabeu, who was being honoured with a friendly match against Al Sadd on Thursday.
'11 Bale' has since been removed from the website, with the vacant shirt number disappearing completely.
