David Moyes was spotted at Chesterfield's 1-1 draw against Fleetwood over the weekend.
According to the Sun, the Manchester United boss was running the rule over 21-year-old Darikwa, who along with the Red Devils has reportedly been attracting interest from Tottenham, West Ham and Fulham.
Manchester United boss Moyes was keen on Darikwa during his time with Everton and according to the Sun would have tried to sign him for the Toffees were he not subsequently named as Sir Alex Ferguson's successor.
The reigning Premier League champions may have a fight on their hands if the likes of Tottenham make a move for the talented youngster, and Chesterfield chief Paul Cook conceded the club may not be able to hang on to one of their most-prized assets for too much longer.
"Tendayi is a lad we know clubs are looking at," he said.
“Will someone take him soon? That’s out of my hands.
“But certainly, as a young player, there will not be many better around the country.”
Should the likes of Manchester United or Tottenham opt to make a move for the Nottingham-born ace in January, they will likely have to cough up around £1.5 million.
