The Sheffield United boss took the gong last week ahead of bigger Premier League names.
McMenemy wrote for the Daily Echo: "Saints supporters of a certain age will remember that he signed for us as a schoolboy around the time I started what are now called academies in London, Bristol and on Tyneside.
"Chris was recommended to me by an old friend in Sheffield. He spent five years with us from the age of 16 without quite making it before forging a career with Sheffield United, and then the likes of Rotherham, Notts County, Bradford and Halifax.
"He did the same as a manager, cutting his teeth at lower levels, something I've always recommended, at the likes of Alfreton Town, Halifax, Oxford and Northampton, where he won the League Two title three years ago.
"Now he has won the prize of Premier League football at the club where he started out after leaving us."
