The now 34-year-old came close to leaving Old Trafford and joining Real Madrid when he was at the height of his powers back in 2015.
De Gea ultimately remained at Man United, and the Spanish giants went on to sign Thibaut Courtois from Chelsea, who went on to become a legend at the club.
Speaking in an interview with Italian outlet Cronache Di Spogliatoio, De Gea said, "I will speak about all of that when my career is over. When things don't happen, it's for a reason.
“It was close but the transfer wasn't completed... Personally, it went well because Manchester is my home."
