Antonio Conte watched from the stands as Tottenham beat London rivals Fulham 3-0 at Craven Cottage.
The Chelsea boss was spotted at the game taking notes alongside former Blue and current coach Carlo Cudicini.
Conte may have been at the Cottage to personally scout Fulham’s young star Ryan Sessegnon who is attracting attention from Premier League clubs despite his tender age.
The 16-year-old began the game on the bench, but was thrown on in the final 35 minutes as Fulham were chasing the game.
Sessegnon has been linked with a move to greener pastures with Liverpool, Manchester United and Arsenal all credited with an interest in the teenager.
Conte will likely face serious competition for Sessegnon should Chelsea chose to move for the youngster.
The Chelsea boss was also watching two on-loan Blues with Tomas Kalas and Lucas Piazon among Fulham’s ranks.
Centre-back Kalas started the game while fellow 23-year-old Piazon watched the match from the bench.
Fulham were unable to stop Harry Kane scoring a hat-trick as Tottenham ran out comfortable winners to secure their place in the next round of the FA Cup.
Former Crystal Palace boss Alan Pardew was also at the game sitting with Leonid Slutsky.
Slutsky has been linked with a post at Chelsea in recent weeks with the Blues said to be keen on bringing the Russian into the analytics department.
