However, the Blues were NOT watching the highly-rated Franck Kessie — but his team-mate, Andrea Conti.
Atalanta have been a revelation in Serie A this season and the Lecco Eurostar — as he has been named by some of his team-mates — scored the only goal of the game as his side beat Crotone 1-0.
And Conti will be available at the relatively low price of £12.8million.
Victor Moses has excelled for Chelsea in that right-wing back role — and his performances even saw him touted with a move to Barcelona.
But, should the Nigerian international suffer an injury, the Blues don’t have a suitable replacement in their squad.
Conti made his professional debut in a 1-0 Coppa Italia home loss against Savona in 2013 while on loan at Perugia.
Two years later, he played his first match for Atalanta and has become a regular this season.
And they are just three points behind Napoli in that final Champions League position.
