The skipper scored a goal of the season contender from 30-yards to get the show on the road after 25 minutes, sending Dons on course for their first league win of the season.
But Jordan Clark’s equaliser with 20 minutes to go threatened Dons with yet another draw before Aaron Collins’ penalty seven minutes later ensured a win for Paul Warne’s side.
A night-and-day performance compared to last week’s defeat to Reading, here’s how we rated the players.
9. Ibrahim Fullah - 6.5
Wanted to get on the front foot in his first league start, but often got drowned out by Luton's busy midfield | Jane Russell
10. Top Don: Alex Gilbey - 8.5
A goal of the season contender already, but his work-rate, and ability to drag his team-mates along with him made him the stand-out | Jane Russell
11. Sam Nombe - 6.5
Ran a lot of channels again, putting in some decent balls he'd have love to get on the end of | Jane Russell
12. Aaron Collins - 7
Ten on the board now for the Welshman, who proved the coolest man in Stadium MK with the penalty to win it | Jane Russell
