"It's about getting over the line at this stage of the season," insists Chopper
It took grit, determination and a penalty decision to go the Lions' way to edge past Peterborough on Tuesday night.
And while manager Neil Harris admitted the 1-0 victory was far from pretty, he is happy to see his side 'win ugly' if it means they cement their place within the top six.
"It's not about being the better team at this stage of the season," Harris told millwallfc.co.uk
"It's not about having the most possession or even the most chances. It's about getting over the line."
MK Dons will travel to The Den seeking to extend their unbeaten spell to three matches, having scored twice against the defensive-minded Bradford City in a hard-fought draw this week.
"It's going to present another difficult test for us," Harris added.
"MK Dons are a similar team to Peterborough. They are very good with the football, very attack-minded and very unpredictable going forward.
"It's important that we are at our best. We have just got back into the top six and we have to be at our best because we can't afford to be slipping out again."
Goalkeeper Jordan Archer is again unlikely to be available for selection as he recovers from an injury sustained in the Emirates FA Cup win over Leicester City earlier this month.
In his absence, Tom King has slipped seamlessly into the gloves and helped to extend Millwall's incredible record of clean sheets to 9 games.
Jed Wallace and striker Steve Morison will be assessed prior to kick-off as they look to shake off knocks that saw them miss the 1-0 victory over the Posh.
Meanwhile, The Dons are expected to travel without Chuks Aneke, after the forward limped off with a hamstring injury at Northern Commercials Stadium on Tuesday night.
