Emerson will be offered a more lucrative deal, which will see his wages rise from £3.5m to £4.5m plus add-ons, reports Gazzetta dello Sport.
Emerson’s current deal expires in 2022, but the Blues are also keen to extend his deal by a further year and secure his long term future at Stamford Bridge.
The 25-year-old joined the club for £18million from Roma in January 2018 but only became a regular in the first team towards the end of last season.
Marcos Alonso had previously held the left-back position, but Emerson is now the undoubted first choice.
Emerson has started every game for Chelsea so far this season and featured for Italy in their 3-1 victory over Armenia.
