Solihull Moors were 2-0 victors on a blustery evening at the J Davidson Stadium.
In a dominant display, Sbarra got the ball rolling with a smart finish before Osborne doubled the visitor’s lead with a pinpoint effort from just outside the area.
Moors manager Shan made three changes to the side who overcame League Two Scunthorpe United 3-2 in the FA Cup on Sunday.
Centre-half Jordan Piggott was handed his full Moors debut, as Tyrone Williams moved to right-wing back to fill the void left by Cameron Coxe who was away on international duty.
On the opposite flank, Mitch Hancox reverted to a more familiar left-wing back with Jordan Cranston given the night off, allowing the evergreen Darren Carter to come back into the side.
A final change saw Moors playmaker Jamey Osborne start in place of Callum Maycock who dropped to the bench.
Full of confidence, fresh from taking the scalp of Scunthorpe, Moors dominated the opening exchanges with Shan’s side camped in the Altrincham half right from the off.
And it really was only a matter of time before the first goal arrived, and just before the 20-minute mark, it did, courtesy of Sbarra.
A misplaced header by Joel Senior dropped to Osborne who drove into the box, picked out Sbarra and the midfielder showed composure to fire it home.
Shan’s men had been the better side but it was a gift from the home side. One, which inexplicably, they repeated moments later, as another error led to Moors’ second.
Again Osborne was the beneficiary of a loose ball, but this time provider turned scorer as Moors’ number 10 picked his spot and curled it beyond Tony Thompson in the home goal.
Moors had been ruthless, they were now in complete control, having made their hosts pay for two incredible lapses in concentration.
Hancox almost added a third, when Osborne’s floated cross found the defender at the back post but Thompson collected his header comfortably.
It was one-way traffic, with Ryan Boot’s goal rarely under threat and Moors continuing to patiently build from the back.
Altrincham started to find their feet towards the close of the half but no chances were created and Moors went in 2-0 to the good at the break.
Half-time: Altrincham 0-2 Solihull Moors
Moors started the second half with similar energy to the first. Some quick thinking from Stephen Gleeson saw him slip his free-kick down the side for Hancox, but Thompson was out quickly.
The midfielder then performed heroics at the other end, sliding in at the last as the hosts looked like they were about to find a way back into it.
Moments later, a trademark Osborne run saw him round his markers, get to the byline, before being taken down inside the area. The referee was unmoved, despite it looking a stonewall spot kick.
The magic man was on top form all evening and repeated his trick in the first half of finding Hancox in the centre. However, the flying full-back couldn't keep his header down.
Moors had to withstand a few nervy moments at the back but, all in all, they cruised through the second half on their way to the three points.
