Millwall toppled Bournemouth, Watford and champions Leicester without conceding a goal at the New Den to reach this stage of the competition.
“They’ve been very good in their previous ties and we’re aware of that,” said Mauricio. “We have a big respect for them and it will be very tough. It’s an important game for us.
“For us, it’s not just a game against Millwall, it’s the chance to go to the next round and a semi-final at Wembley. That is a massive aim for us, a massive challenge. We respect Millwall and we must try to give our best to win the game.”

Millwall are up to sixth in League One after a run of 17 matches unbeaten in all competitions - that’s the same number of matches we’re unbeaten at the Lane in all competitions this season, winning 15.
“First of all, it’s important we show big respect for Millwall and give our best if we want to be at Wembley,” added Mauricio. “We’re confident but know we need to fight and give our best on Sunday to win.
“In football, you need to give your best in every training session every day and then give your best every time you play.
“For me, it’s the same playing against a team in the Premier League, in Europe or in the FA Cup. The most important thing is to realise that every time you get the opportunity to play you must give your best.
“We need to play with intensity, aggression and a high tempo. That’s the reason we’re unbeaten and play so well at White Hart Lane, so we need to keep the same ways, that’s key for us.”
