The Blues are reportedly interested in Hertha Berlin winger Javairo Dilrosun, according to Calciomercato via Sport Witness.
The 21 year old winger has scored three goals and has two assists in just six Bundesliga games this season.
His form for Hertha Berlin has also reportedly alerted Bundesliga giants Borussia Dortmund.
With the contracts of Pedro and Willian expiring at the end of the season and the club yet to renew, it seems Chelsea want Dilrosun as a replacement.
Dilrosun plays on the left wing which is also favoured by Callum Hudson-Odoi and Christian Pulisic.
