Players encouraged to "play with freedom" at White Hart Lane
Lions boss Neil Harris says his side are relishing the underdog tag in the countdown to Sunday's anticipated clash at Tottenham Hotspur.
Millwall are at long odds to produce another Emirates FA Cup upset this weekend despite knocking out AFC Bournemouth, Watford and Leicester City without conceding a goal against Premier League opposition.
"I think the experts have written us off," Harris told millwallfc.co.uk
"But being the underdogs with our backs against the wall is when we are at our best.
"Tottenham have a fantastic manager who wants to win a trophy, but he is also taking the competition seriously because the fanbase wants him to put out a strong team because of their endearment to the Emirates FA Cup."
Goalkeeper Jordan Archer is an "outside chance" to face his former club as he recovers from a knock suffered during a Man of the Match performance against Leicester City last month.
His absence has paved the way for replacement stopper Tom King, who has conceded just one goal since making his Football League debut against Chesterfield on 21st February.
"If Jordan isn't fit then we'll continue as we are this weekend," Harris added
"Everyone else is in full training. Steve Morison and Jed Wallace came off the bench last Saturday and had an input, so there are decisions to make for me going into Sunday's fixture."
Meanwhile, Tottenham are again expected to be without injured left-back Danny Rose and Argentine winger Erik Lamela, who missed Spurs' 3-2 victory over Everton on Sunday.
