Lambton joined Leeds as a trainer in November 1957
as an assistant to Raich Carter after coming to public attention
as a fitness trainer for British boxers. When Carter's contract was not
renewed, Lambton was made acting manager, before finally having the appointment
confirmed in December 1958.
In such a short time in charge, he had little influence on the way things
were done at the club - but his signing of Don Revie on the playing side
was to be one of the most significant events in the club's history. After falling
out with the board, he left in February 1959, and went on to briefly (for 3 days!)
manage Scunthorpe, before enjoying a longer spell at Chester.
