The Derby emissary is said to have made the short trip to Lincoln City to watch Ampadu in action for Chelsea's Under-21s, who were knocked out of the Football League Trophy on penalties.
And it is claimed he left with 20 minutes remaining, having seen enough of the 17-year-old, for whom his enthusiasm 'spoke volumes'.
The London Evening Standard warn, however, that if Derby are planning a summer move for Ampadu it will almost certainly fail.
Derby loan a logical next step?
Despite his tender years, Ampadu, a centre-back-cum-defensive-midfielder, has already made 19 senior appearances - including six for Chelsea, for whom he signed from Exeter City in July 2017.
The chance to add to that early experience at a club like Derby, for example, could be a logical next step in the Wales international's career - especially with the Rams on course for promotion to the Premier League.
