Northampton manager Ian Sampson has promised FA Cup opponents Fleetwood Town a tough contest at Sixfields on Saturday.
Sampson is a veteran of FA Cup shocks with the Cobblers - most notably a televised defeat at Canvey Island in 2001 - and is determined to beat the Blue Square North side.
He said: "We are delighted to have a home tie but it won't be easy at all.
"As a player I was a killer in the FA Cup and I was killed a few times so we will take nothing for granted at all.
"It's a big game for them, they are a full-time outfit so they will be fit and they will really come at us.
"The players are professional enough to know that it's a big game for the club and we will be 100% focussed on winning through to the next round."
