The South London Press went along to watch the friendly that never was last Saturday and found solid defending by the Lions helped to keep their visitors at bay.
Goals at either end of the game from Danny Spiller and Chris Hackett gave Willie Donachie's team their first win of the 2007-08 pre-season and but for some rusty finishing, in the absence of Darren Byfield, the Lions might have won by an even greater margin.
Aldershot, bossed by former Lion Gary Waddock, kept the pressure up for sustained periods but could only make the hosts sweat once or twice.
Millwall keeper Chris Day had to stretch for a third-minute John Grant effort and a 38th-minute Ben Harding drive, but otherwise their threat was snuffed out in the first half. Instead, Neil Harris nearly made the breakthrough as early as the fourth minute, jinking around Shots keeper Nikki Bull, and flighting the ball over for Ben May, but the striker's header was cleared off the line.
Four minutes later, though, Harris again did the damage, getting amongst the visitors' back line and doing enough in front of Bull to let the ball run for Spiller. The midfielder was in enough space to assess his choices and place a neat strike beyond Bull and into the far right-hand corner, for his first goal in a Millwall shirt.
Alan Dunne's attempted lob was later charged down and Spiller's vicious cross-shot was deflected over by Harris.
Spiller was also the architect of one of the best chances, in the 27th minute, when he put Ryan Smith through, but Bull did well to smother the winger's effort, as May waited in vain for a cutback.
Spiller nearly sneaked around the keeper two minutes into the second half,but again Bull blocked well. May's 52nd-minute header from Dave Brammer's free-kick dipped narrowly over,while the ex-Gillingham midfielder poked Harris' cut-back wide seven minutes later.
Day made the most spectacular save of the afternoon, from Rob Elvins' low long-ranger as the managers tried out different combinations in the last half-hour.
Only two headers over the bar at either end registered on the chance-o-meter, one from Rhys Day and one from Paul Robinson, before 80th-minute sub Hackett sealed the game.
Another sub, Scott Barron, clattered as he set off on a run down the left channel, pushed his quickly-taken free-kick forward for the winger.
Nothing seemed on, but Hackett kept running as defenders skittled back and when he got close enough, instead of sweeping into the path of an arriving striker, he stroked the ball precisely inside the far post from a narrow angle.
That strike capped a workmanlike 2-0 win, but one that's given Donachie's squad a solid boost in time for the business end of pre-season preparation, with matches against another, more serious Hampshire outfit, Southampton and Sierra Leone.
With only two weeks to go before his team gets down to proper football, that will be a relief and this game showed how much the players wanted to put the awful 2-0 defeat a week ago at Ebbsfleet behind them.
A third, even more serious Hampshire outfit, the county police force, had ensured - by trying to charge the hosts £10,000 for security - that the originally scheduled game at Aldershot was axed.
But it was Millwall's boys in blue who still came out on top.
