The Spanish stopper has been linked with a move away from Old Trafford in recent months and is preparing to leave the club this summer.
According to the Daily Mail, the 30-year-old is ready to call time on his United career after a decade with the Red Devils and his camp have now begun sounding out potential suitors.
No transfer fee has been mentioned yet, although United are believed to want a fee in the region of £50m.
De Gea's £375,000-a-week wages could be a stumbling block in the current financial climate and the Spaniard may have to accept a reduced wage package if he were to leave United this summer.
Since joining United in 2011, De Gea has made over 430 appearances for the club and has kept 153 clean sheets. body check tags ::
