Football Leaks have revealed the contract that David de Gea was going to earn at Real Madrid before his move to the La Liga giants from Manchester United collapsed on deadline day last summer.

Having also disclosed details of other deals like the record move of Gareth Bale from Tottenham to Los Blancos in 2013, the website revealed that the Spanish keeper was due to commit his future to the Santiago Bernabeu with a six-year-deal, earning €11.8m (£9.1m, $13.1m) a season plus add-ons depending on trophies.

Real Madrid and Manchester United reached an agreement on deadline day for the transfer of the keeper after a summer of long speculations, with De Gea being even left out of the squad by Louis van Gaal for the first six games of the campaign because the manager believes he was not in the right place to focus on football. Los Blancos then also agreed to send Costa Rica international Keylor Navas to Old Trafford in a separate deal for United to fill the gap of the Spaniard.

But the deal failed as paperwork did not arrive at La Liga headquarters on time, with the La Liga giants' president Florentino Perez blaming Manchester United for the inexperience of their board while the Old Trafford club said that Los Blancos were responsible for being too slow in processing the contracts.

De Gea, whose contract at United was due to expire at the end of the current season in June 2016, opted consequently to commit his long-term future to United by signing a four-year deal worth £200,000 a week (£10.4m-a-season) according to the Daily Mail. Some reports then suggested that the Spaniard was forced to put pen on paper on a new deal to avoid being frozen out the whole season while United agreed to include a release clause in his contract to facilitate a future move to Real Madrid.

Football Leaks have failed to put light to that questions, but as released in full and Spanish by Sport, detailed that De Gea was due to earn €11.8m a season at Real Madrid in a six year deal until June 2021, with a big unspecified bonus as incentives.
