De Gea nearly left United in 2015 but for the deal to break down at the last minute on deadline day. Real have never given up trying to sign him, however, and Diario Gol say the Spanish international reciprocates their interest.
Real Madrid are so desperate to sign him but they may have more luck playing the waiting game. De Gea has less than 18 months on his deal which could panic United into cashing in this summer or risk losing him for free next year.
The Spaniard appears happy at Old Trafford but until his contract has been extended his future will remain uncertain. United will be worried if no progress is made this summer.
