ANDY RITCHIE is proving to be a real Diamond Geezer!
He received a huge standing ovation from the greatly-expectant Town faithful before his first match in charge at the Galpharm.
And the players responded magnificently to record their biggest win of the season, their first in seven, with goals from Michael Collins (who was sent-off late on), Mark Hudson and two, including a penalty, from Luke Beckett to ensure there will be no more jangling nerves with League I status now guaranteed.
Ritchie demanded his players be more positive and employed them in a new diamond formation, with Andy Holdsworth sitting in front of the defence, while the superb Michael Collins relished his role to roam in support behind strike partners Luke Beckett and Gary Taylor-Fletcher.
It was a system that Town took about 20 minutes to get used to, but when it clicked . . . it clicked!
Collins was inspirational. He was booked on five minutes for dissent despite shirking off three shoulder charges as he scythed across Millwall's midfield.
He then rifled in the 21st-minute equaliser after Darren Byfield had poked Millwall in front on eight minutes.
But two minutes from time he was given a second yellow after dreadful referee Darren Deadman deemed that Collins' playful pat on Ryan Smith's head - after the Derby loan-man (who appeared full of gamesmanship) had lunged at Joe Skarz to the fury of Taylor-Fletcher - was a threatening gesture.
For the first 15 minutes, Willie Donachie's outfit were quick and clever and when Dave Brammer launched a corner on eight minutes, skipper Paul Robinson flicked it on for Byfield to slot in.
Town could have capitulated, but instead there was constant talk between their players to get the new diamond system working.
And after Collins' equaliser - made when Taylor-Fletcher showed a quick turn of pace to pick out Hudson, who touched the ball on for Beckett to flick it out for the Eire Under 21 cap to fire home - Town never looked back.
Soon after, Collins' beat former Crystal Palace old boy Richard Shaw to force a near-post save from keeper Lenny Pidgeley.
And Collins almost created a goal on 34 minutes, launching a beautifully flighted ball straight to Taylor-Fletcher, but his powerful header was turned onto the bar.
Town were slipping into sixth gear and not even half time could put them out of their stride.
Industrious Andy Holdsworth and Hudson thrived in the midfield, getting forward at every opportunity, while Jon Worthington was the stabilising lynchpin.
And with right-back Frank Sinclair showing his younger teammates that he still has the legs to surge down the wing, Millwall were left baffled.
On 58 minutes, Town went ahead again when Beckett saw a goalbound effort cleared off the line by Robinson but only to Hudson, who launched a belter to bulge the back of the net.
Collins had a header cleared off the line moments later before Town stopper Matt Glennon denied Alan Dunne's effort in a rare Millwall attempt on 70 minutes.
A minute later, Beckett fired in Town's third from the penalty spot, blasting low and hard inside the left post after Danny Senda brought down Hudson.
And on 78 minutes leading strike ace Beckett took his tally for the season to 15 when Worthington's well-weighted pass was fired home to the delight of the home faithful in a crowd of 9,406.
Dunne presented the 349 travelling contingent with a late consolation after Smith, who was constantly booed by Town's supporters after Collins' dismissal, had produced a strong run and cross which was slotted in from close range.
It hardly mattered as Ritchie's rejuvenated and rampant side rewarded their new gaffer with a brilliant win for his first home game in charge.
