"It will be tough and we're taking nothing for granted," said the full-back who signed a new deal this week. "This is something we've faced already this season and it's up to us to deal with it."
Ben is referring to a thrilling fourth round tie against League Two side Wycombe, who arrived in N17 on the back of a 16-match unbeaten run and pushed us all the way. Indeed, we were 3-2 down with time running out before late, late goals from Dele Alli and Heung-Min Son turned it around.
League One challengers Millwall arrive at the Lane on a run of 17 matches unbeaten in all competitions, including a hat-trick of Premier League scalps at the New Den in Bournemouth, Watford and reigning champions Leicester City last time out in the fifth round.
You could say we don't want to get bitten again, this time by the Lions. "It’s about us and we have to focus on our game, make sure our preparation is right and if it us, hopefully get another win," said Ben, who knows success will mean a big semi-final occasion at Wembley.
"That could be something special but we’re not looking too far ahead, just focusing on the game in hand," he added.
