The Bolton Wanderer is rumored to cost the relegated English side as much as 2 million pounds in add-ons if they regain their status in the Premiership.

The Tunisian, who will only be transferred if granted a work permit, would link up with former Bolton teammate Bruno N'Gotty at Birmingham.

Jaidi joined Bolton from Tunisian side Esperance in 2004, and made 51 appearances in his time with the club.

The seasoned defender has represented his country at two World Cup tournaments, including the 2006 edition in Germany, and won the African Nations Cup with Tunisia in 2004.
