David de Gea was set to earn £9.2 million a year on a deal to 2021 at Real Madrid had he completed a move from Manchester United last summer, according to the Football Leaks website.

Man. United and Real Madrid in August agreed a £29 million transfer that would have seen the goalkeeper swap Old Trafford for the Bernabeu, but the proposed switch fell through after the requisite paperwork was not submitted before the Spanish deadline.

This week, Football Leaks published a document it claims is the contract De Gea was due to sign at Madrid.

It shows the Spain international would have received a figure of €11,818,182 (£9.2 million) for each season from 2015-16 to 2020-21.

There is also mention of a break clause of €500 million (£388 million), which keeper De Gea would have been obliged to pay if he walked out on his contract.

Only a few days after the move failed to materialise, United announced De Gea – who joined them from Atletico Madrid on a five-year deal in 2011 – had signed a new four-year contract, with an option to extend for a further year.

That deal was reportedly worth £200,000 per week. The figures from the Football Leaks document equate to around £176,000 per week.
