Terry Butcher
A former England captain but now part of George Burley's Scotland camp, working as assistant manager, Terry will be giving his views to Setanta Sports throughout the season.
After making his name as an Ipswich Town stalwart under Sir Bobby Robson, he joined Rangers to make his mark in Scotland.
By winning the title three times in his four years in Glasgow, he cemented his place in the club's illustrious history and has remained heavily involved with the game north of the border after managing Motherwell.
The 49-year-old won 77 caps his country and also appeared for Coventry City and Sunderland later in his distinguished playing career.
Rangers need a reaction
The big thing to take out of the game is how Rangers will react. Rangers lost seven points last season when they were ahead of Celtic, so it can be turned around but for me it is how Rangers react.
Celtic got a reaction from when they lost at home, so Walter Smith will be looking for his team to react in the same way Celtic did.
It is not over, but Rangers have given themselves a hard job.
Many people were hoping the gap would be down to one point, but it is now seven and it is a big gap.
Celtic can afford to lose the remaining two Old Firm games and still be a point ahead.
