Manchester United chief David Moyes was an interested onlooker during Chesterfield's draw at Fleetwood on Saturday amid suggestions that Moyes was there to cast an eye over Darikwa.
The 21-year-old is regarded as one of the best young players in the lower leagues and a number of Premier League clubs have been credited with an interest in his services.
Cook is aware of the growing interest Darikwa and is bracing himself for offers for his prize asset when the transfer window reopens in January.
"Tendayi is a lad we know clubs are looking at," said Cook.
"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."
