Chelsea have opted against using the buy-back clause for winger Jeremie Boga despite becoming one of Serie A's most exciting players since joining Sassuolo in 2018.
The west London club have negotiated a sell-on clause with Sassuolo ahead of an expected move in the next transfer window, with fellow Serie A club Napoli thought to be interested in the 23-year-old.
Boga came through the Chelsea youth system but played only 18 minutes of competitive football for the first team and spent several spells out on loan before a permanent move to the Serie A in 2018.
