Leicester City and Queens Park Rangers are reportedly interested in signing Efe Ambrose from Celtic.
The Nigerian defender has made 24 appearances for the Scottish side in all competitions so far this season.
Leicester and QPR are both said to be looking for new additions to their squads as they look to move away from the Premier League relegation zone.
It appears that Celtic would be willing to allow Ambrose to leave the club in January.
According to The Sun, the 26-year-old would consider a loan move.
Ambrose moved to Celtic Park from Israeli side FC Ashdod in 2012.
