Sky Sports understands that Chelsea youngsters Sam Walker and Aziz Conteh have agreed contract extensions with the Blues.
The pair are believed to have committed their future to the Blues for another two-and-a-half years, taking them through to the summer of 2014.
Walker is a highly-rated goalkeeper who is currently taking in a loan spell at League One outfit Yeovil.
All of his senior experience to date has come away from Stamford Bridge, with loan stints having also been taken in at Barnet and Northampton.
The 20-year-old is, however, held in high regard at Stamford Bridge and was a key figure in Chelsea's FA Youth Cup success in 2010.
Conteh was also part of that cup-winning side and continues to catch the eye of the Blues' coaching staff.
The promising full-back is yet to make the step up from reserve level to the senior fold, but the England U19 international is considered to be a potential long-term replacement for Ashley Cole.
