N'Golo Kante and Chelsea remain at deadlock over new contract talks.
The London Evening Standard says Kante's extension is on the agenda, but the midfielder is reluctant to accept a two-year contract with an option for an extra year.
The 31-year-old, whose season has been wrecked by injury, is hoping for a three-plus-one deal.
The focus on players whose deals expire this summer has left those with 18 months on their contracts in the dark.
Mateo Kovacic and Conor Gallagher have had no contact on new deals, amid speculation that they could also be moved on in the summer.
