Chelsea youngster Ian Maatsen is said to have rejected several contract offers from the club.
The Stamford Bridge team want to ensure the young left-back is their player for years to come.
However, Maatsen is not happy at his lack of game time, leading to him rejecting any attempts to get him to sign a new deal.
Per football.london, if the left-back does not sign on fresh terms before the end of the season, he may be sold.
Maatsen's deal was extended by one year, which means Chelsea can sell him for a fee next summer.
Blues boss Mauricio Pochettino has preferred using Levi Colwill at left-back this season.
