Paul Jewell is fully aware of the challenge his side face in their Carling Cup semi-final against Arsenal.
Town go into the second leg at the Emirates 1-0 up thanks to Tamas Priskin's goal at Portman Road a fortnight ago and have the chance to book their first visit to the new Wembley.
Jewell knocked out the Gunners at the same stage of the competition five years ago en route to guiding his Wigan side to the final and could be responsible for an even bigger shock this time around.
But the Barclays Premier League outfit have looked ominously back to their best in the last 10 days to leave Jewell in no doubt that his side are up against it.
He said: "We've got to respect them, they're a great team, they've got great players, a great manager, it's a great club.
"But it's 11 against 11 and we've got to see if we can pull off a huge upset."
