Manchester United legend Bryan Robson has pleaded with Sir Alex Ferguson to carry on managing the club for another five years.
The 70-year-old has won 37 trophies during his 26 years in charge at Old Trafford, and guided his side to a 3-2 win over rivals Manchester City on Sunday.
Robson firmly believes that the Scot can prolong the club's era of dominance for at least another half a decade.
"He's just incredible," Robson told talkSPORT.
"You go to the training ground and he's always first in at half seven in the morning. He's just got so much enthusiasm for the job and there is drive for these big games. He just relishes these sort of challenges.
"He's rebuilt the squad probably four or five times at United in 26 years and the success just goes on, hopefully he'll be about for another five or six years so that success stays with the club."
United host Sunderland on Saturday.
