KENNY Jackett says Millwall cannot afford to underestimate giant killers Luton Town in the fifth round of the FA Cup next month with a place in the quarter finals at stake.
The Hatters beat Premier League side Norwich City on Saturday to progress and Jackett is under no illusions as to the size of the task that awaits the Lions in the next round.
"Playing a Conference side away is a tricky tie," he said. "It was a phenomenal win for them against Norwich, absolutely phenomenal.
"In the end, we have an opportunity to get through to the quarter finals and that is exciting in itself. But it's not a given that we can do it.
"They are a side that we have picked up and watched this season so I know it will be a tricky tie. The stakes will be great and these are exciting times for both clubs."
