Chilwell has fallen in the pecking order behind Marc Cucurella in the Blues' setup and his lack of game time last season also led to him being left out of Gareth Southgate's squad for Euro 2024.
The 27-year-old is one of several players who have been excluded from training with the Chelsea first team, having been deemed surplus to requirements under new boss Enzo Maresca.
Among the other outcasts at Stamford Bridge are Raheem Sterling, Trevoh Chalobah, Djordje Petrovic and Carney Chukwuemeka, while Conor Gallagher managed to secure a move to Atletico Madrid earlier this month.
Man United drop interest in Chilwell deal
Chilwell was widely reported to have been offered to Manchester United in recent days, with the Red Devils looking to bring in a left-back before the transfer deadline owing to injuries to Luke Shaw and Tyrell Malacia.
However, it now seems increasingly likely that the 27-year-old will remain in West London after Friday's deadline, with the Daily Mail revealing that United have opted against pursuing a deal for the England full-back.
The report adds that finding Chilwell a suitable buyer in the next two days will be all the more difficult for the Blues due to his wages, which is currently set at around £200,000 a week.
Chilwell joined Chelsea from Leicester City in a deal worth £50m back in 2020 and helped the Blues win the Champions League title in his first season at Stamford Bridge.
His current contract runs until the summer of 2027, having put pen to paper on a new deal, which included a salary increase, last April.
Chelsea not done with summer transfer business
While Chelsea have been the biggest spenders in this summer window, there are strong indications that the Blues are not done with their transfer business just yet.
Sky Sports report that Maresca's side are attempting to make a late move for Brentford striker Ivan Toney ahead of Friday's transfer deadline.
The Bees' attacker is looking to depart the Gtech Community Stadium before the window closes and has been heavily linked with a move to Saudi Pro League side Al Ahli.
Toney was left out of Thomas Frank's squad for the first two Premier League games this season and was also omitted for the team's trip to Colchester United in the EFL Cup in midweek.
