Bolton Wanderers boss Owen Coyle has slapped a £30 million price-tag on defender Gary Cahill.
Cahill's last chance to force his way back into Fabio Capello's plans comes at home to Birmingham tomorrow.
Coyle said: "I'm delighted to have him but there will come a time when someone outgrows a club. If someone offers £30m for Gary Cahill then you would probably say that is fair.
"He is at the top level and that is why it would have to be something like that.
"It would be wrong if we stood in his way."
