Chelsea centre back Trevoh Chalobah is attracting interest from Fulham.
The west London rivals are exploring a loan deal for the 24-year-old who has yet to play this season after a hamstring injury.
The defender is expected to be fit by the end of the month.
Chelsea would be willing to sell as they look to raise funds for a left-back and striker, particularly as Chalobah is homegrown and help with the Premier League's Financial Fair Play FFFP rules.
Blues boss Mauricio Pochettino has settled on a back four of Levi Colwill, Thiago Silva, Axel Disasi and Malo Gusto.
Bayern Munich, Roma and Tottenham are also monitoring developments.
Chalobah has made 63 appearances in all competitions for Chelsea since returning to Stamford Bridge in the summer following loan spells at Ipswich Town and Huddersfield in the Championship and at Lorient in Ligue 1 .
Fulham are also among the clubs monitoring developments with Armando Broja who Chelsea are willing to sell for near to £50million by Chelsea.
Wolves are also keen on signing Broja during the January transfer window.
Much will depend on Chelsea's own search for a striker as they explore the market for late opportunities.
