Details of De Gea's move to Manchester United leaked| OPEN FAST

Manchester United agreed the deal to sign David De Gea from Atletico Madrid almost a year prior to the completion of the transfer, according to leaked documents published by Football Leaks. 

The Spain international swapped the Vicente Calderon for Old Trafford in June 2011 but a transfer agreement dated October 28, 2010, shows that United had already put an €18 million deal in place.

But a subsequent letter, dated June 23, 2011, revealed a change in transfer agreement which meant United actually spent €17,125,000 on De Gea in a one-off sum.



The leaked information claims that United agreed to shell out €500k for every 25 appearances made by De Gea, which runs up to 100 matches. 

United also have to pay Atletico €250k each time they reach the Champions League group stages, and also if they reach the last 16 and for every quarter-final appearance.

Atletico also have a clause which entitles them to €1m every time United win the Premier League with De Gea, which was the case when they lifted their 20th crown in 2012.

De Gea was on the cusp of returning to Spain but to Atletico's bitter rivals, Real, last summer, only for a deal between them and United to fall through at the final hurdle. 

The leaked documents also claim that Atletico will receive €5m if United sell De Gea before June 30, 2016.
