Chelsea are drawing up a new contract offer for Willian.
The London Evening Standard says talks have already begun and with the player happy in west London, Chelsea are hopeful a £100,000-a-week contract extension will be announced by the new year.
Willian has just over two years left on his contract at Stamford Bridge, but having impressed during the early part of the season, the Blues are keen to tie him down to a new deal.
His Brazilian teammate Ramires committed his long-term future to the club last month, signing a deal until 2019.
