'Doc', who made his name in a televised cup tie at Kenilworth Road in 1999, had big cup clashes against Sunderland and Fulham in his time at Luton.

Now it's another test in the Worthington Cup third round against Stan Ternent's First Division outfit live in front of the Sky Sport cameras.
"Burnley will give everything," he stressed. "It's one of those ties that when I was with Luton we'd really look forward to as soon as the draw was made. It's a massive game for them to impress, they'll be up for it and we'll have to match that.
"If we'd have got this tie when I was at Luton we'd be right up for it. It's a huge game for them.
"It's a no-win game for us although I suppose we can win by winning! Everyone expects us to win and it will be headlines if we lose.
"Sky Sports aren't idiots, they are there for a reason and they must believe there is a chance of an upset. They'd have looked at the big teams going away from home, big crowd, a tough game for us and we'll have to be up for it.
"We been good in both cups in recent years though. It's probably because we've always had our serious head on for both cup competitions. We have to match them physically and hopefully then our ability will take us through."
Gary Doherty knows more than most about how Burnley's players will approach Wednesday's Worthington Cup tie at Turf Moor.
