Crystal Palace’s Wales international centre-half Danny Gabbidon is the latest defender the Blues and several other clubs are reported to be keeping tabs on.
According to Sky Sports, Town, Norwich, Bolton, Leicester and Blackburn are all "monitoring” the 34-year-old’s situation with his contract up at the end of the season and no talks regarding new terms currently underway.
Cwmbran-born Gabbidon, who is 6ft 1in tall, started his career with West Brom prior to spells with Cardiff, West Ham and QPR, before joining the Eagles in September 2012, having been offered a contract by Town earlier that summer.
This season the 47-times-capped defender has been a regular in Palace’s side following their promotion to the Premier League. A drop into the Championship during January seems highly unlikely, although a move away from Selhurst Park may be on the cards in the summer.
