Steve McClaren has stated that he expects to sign an extended contract shortly. His current deal runs out at the end of next season. The new contract will keep him at the club until the end of the 2006/07 season, with no opt-out clause should the England job become available.
If Sven leaves the England post and the FA want McClaren before June 2007 then it is likely Boro could get substantial compensation if they let him go.
