Millwall have been one of the surprise packages in the FA Cup this season, beating the likes of AFC Bournemouth, Watford and Leicester City en route to the quarter-finals of the competition and the Lions have now been rewarded with a clash against local rivals Spurs at White Hart Lane on Sunday.
Millwall clearly head into the encounter as underdogs but rather than being intimidated, manager Harris has stated his belief that approaching the game as second favourites actually suits the League One outfit.
Harris told the EFL Weekly Podcast: "We've got a great bunch of players and they get on really well on and off the pitch. There is a real spirit amongst the group, pretty much what you would expect from a Millwall side.
"We'll certainly take that spirit and togetherness into the weekend when there will be difficult moments in the game for us. As a club, we've had our backs to the wall sometimes and we've always come out fighting.
"Being the underdog is certainly suited to us on Sunday and who knows - that's the beauty of the FA Cup, who knows what could be achieved. We've had tough ties in rounds gone by and we've earned the right to go up against one of the best teams in the country at the moment. We're really looking forward to it.
"We've embraced this competition since round one and we're certainly looking to go and compete against Spurs and to try and impose ourselves on them.
"All due respect to the guys we have played already, I think this takes us to another level. We've been at The Den for each game which has been an advantage and going to Spurs in their back yard certainly makes things a bit more difficult.
"There's also the form that Spurs are in. They have a terrific home record and are in terrific form at the moment with a really talented bunch of players."
