Birmingham manager Lee Clark believes goalkeeper Jack Butland's value will treble if he makes his senior England debut against Italy.
The 19-year-old is in the remarkable position of possibly making his England debut before making an appearance for his club, after spending last season on loan with npower League Two side Cheltenham.
But after representing Great Britain at London 2012, after also being a part of the England squad at this summer's European Championships, Clark believes Butland's value is on the rise.
Clark told the Birmingham Mail: "To be honest with you, I wouldn't want to entertain talk of selling him.
"But you win an international cap, it means are you going to look at a bigger value.
"Six million just gets you a League Two goalkeeper, it doesn't get you a full international - probably treble that, I would have thought."
