Revealed: How much Manchester United are still paying in bonus deals for big-money signing
MANCHESTER UNITED'S bonus agreements with Atletico Madrid over the terms of David De Gea's 2011 transfer have reportedly been revealed.

The Red Devils landed Spain's No 1 goalkeeper from Madrid five seasons ago in a reported £18.9million deal.
De Gea has since developed into one of the world's top-rated goalkeepers and last summer he almost joined Real Madrid.
United tied De Gea down to a new four-year contract last September, handing the 25-year-old a reported £200,000-a-week deal.
To date, United appear to have paid out just over £3.5m in bonuses for the player.
De Gea was on the verge of completing a switch to Real Madrid last summer - which would have earned Atletico £3.9m - but the transfer collapsed on deadline day due to a paperwork delay.
Both clubs blamed the other party for the failed move, which would have seen Keylor Navas move in the opposite direction.
