Bolton already have a £15m minimum fee written into his
contract to frighten Liverpool, Arsenal, Spurs and Everton.
But the price will rise even higher should the classy
centre-half appear for England in South Africa.
Cahill is on the radar of Rafa Benitez and Arsene
Wenger and the Trotters are preparing to sell the 24-year-old to
raise funds for manager Owen Coyle.
The former Aston Villa star signed a new deal last year
under previous boss Gary Megson that erased an £8m clause.
Cahill has been regularly called up to the England
squad by Fabio Capello but remains uncapped.
