Gareth Bale could have cost more than Cristiano Ronaldo, leaked documents suggest.

The full financial details of the Wales star's move from Tottenham to Real Madrid appear to show the fee for Wales international Bale was 91 million euros (£78million) - less than the 96 million Real paid for Cristiano Ronaldo in 2009 - but because the fee was to be paid in instalments the final sum rises to a world record 100.7million euros (£85.1million).

The document also shows that it was agreed Real Madrid would announce the fee as £78million and that Tottenham would not refer to the "economic aspects" of the transfer deal.

Real Madrid have always said Ronaldo is the most expensive player at the club.

The document also specifies that Madrid undertook to ensure that Bale would not make "any negative or derogatory comments regarding Tottenham, the club's chairman, its board and/or any of its employees."

It is understood that Bale's agent is relaxed about the transfer agreement being in public domain as it contains no details about salary or other personal information.

The 26-year-old signed a six-year contract when he moved to the Bernabeu in 2013.
