Chelsea's contract negotiations with Tammy Abraham and Reece James have reportedly stalled.
Matt Law of the Telegraph reported the pair are no nearer to agreeing fresh deals with the Blues after breakout campaigns at Stamford Bridge.
Frank Lampard is attempting to tie down his youthful squad, and new contacts have been handed out to Callum Hudson-Odoi, Mason Mount and Ruben Loftus-Cheek. England international Fikayo Tomori became the latest young player to pen a new contract with the club on December 12.
Abraham has been a sensation since returning from a loan spell at Aston Villa in the summer, and the 22-year-old is now Lampard's first-choice striker.
