Strachan is on a 12-month rolling deal and The Herald says an increased salary has been agreed in principle with Celtic's chief executive, Peter Lawwell, and is expected to be announced before the club unfurl the championship flag at Parkhead against Kilmarnock next Sunday. His backroom team of Garry Pendrey, Jim Blythe and Tommy Burns are also expected to be rewarded for their part in the club's ongoing success.
