Millwall manager Neil Harris has urged supporters not to mar Sunday's FA Cup quarterfinal at Tottenham Hotspur with hooliganism.
The League One side, who have beaten Bournemouth, Watford and Leicester City en route to the last eight, have sold out their away allocation of 3,681 but both clubs expect a large number of ticketless Millwall supporters to come to North London.
The clubs' last meeting, a friendly in 2001, was marred by violent clashes between supporters before and after the game, and police have categorised Sunday's match as "high-risk," while they are continuing to hunt for supporters involved in disorder in Millwall's last-round win against Leicester.
"You want to paint yourself in the right light as a club," Harris told a news conference on Wednesday. "It is a competition that has been good to us this year. We want the focus to be on on-pitch activities.
"White Hart Lane is a football cathedral with a good passionate crowd. It's the last game at the Lane in the cup ... Millwall in town with 4,000 fans. It's going to be an electric atmosphere, one we should all embrace and look forward to.
"Our fans are going to travel in numbers and I want them to enjoy themselves and enjoy an FA Cup quarterfinal occasion, support the team.
"We could have sold it three or four times over because they're proud of the players they see at the moment."
Harris rated goalkeeper Jordan Archer, who has kept clean sheets against all three Premier League opponents so far, as "40-60" against playing but the former Tottenham academy graduate told ESPN FC he is confident of facing his former club.
Archer suffered a tear in his thigh in the win over Leicester and he has not played since.
"To be fit for Sunday has been my aim since the start and I've been outside recently so it's all looking good," he told ESPN FC. "I'm pretty confident but I won't know until closer to the day. As it stands, I'm more than confident I'll be available.
"It's a dream tie to play at White Hart Lane in the last cup game. I've got some old friends, so I was looking forward to the occasion. On the same day [as the draw], I found out the result of the scan. I'm pushing to be fit come Sunday."
