That is according to Italian outlet Gazzetta dello Sport, who claim Chelsea have sent scouts to watch Conti several times this season.
Chelsea representatives were said to be in the stands at the Atleti Azzurri d'Italia on Saturday as Atalanta beat Crotone 1-0.
Blues manager Antonio Conte is reportedly looking to make a move for Conte in the summer, with the 22-year-old reportedly available for just £13million.
The Italy Under-21 international has been key in helping Atalanta to fifth in Serie A, scoring four goals and providing three assists in 22 appearances.
His quality in attack is likely to have caught the attention of Conte, who plays with a right wing-back in his 3-4-3 formation.
The Chelsea chief has played Victor Moses on the right-side of defence this season but has little options should the Nigerian get injured.
Branislav Ivanovic was sold to Zenit Saint Petersburg on transfer deadline day, while Cesar Azpilicueta has been deployed as a centre-back this term.
