Bannan was on target as Sheffield Wednesday beat Chesterfield 4-1 in their League Cup first round tie.
Sheffield Wednesday boss Carlos Carvalhal got the reaction he asked for at Hillsborough on Tuesday, as the Owls ran out 4-1 winners against neighbours Chesterfield in the first round of the League Cup.
Carvalhal made six changes from Saturday's Championship defeat at Preston, with those who remained owing much-improved displays, albeit against lesser opposition.
And while most of them delivered, it was the performance of Barry Bannan which stood out above the rest.

The midfielder scored Wednesday's third goal of the night after playing a one-two with Sam Winnall on the half-way line and surging towards the edge of the 18-yard box, where he picked out the top corner.
But as far as many Owls fans are concerned, Bannan would have been among the top performers even without his goal.
Here's what they have been saying on social media...
Sounds like Bannan is putting in a shift tonight, which is pleasing given he was so poor on Saturday— Simon Morris (@BigAl_simon) 8 August 2017
Shows he's a decent attitude #swfc

Bannan was brilliant, reckon it was his evil twin on Saturday #swfc— Sharpey (@THEsharpey) 8 August 2017
Bannan goal was worth entrance fee alone. And Sammy Hutchinson putting the gloves on! #SWFC— Liam Norcliffe (@LiamNorcliffe) 8 August 2017
Bannan was a different class today... one of the best midfielders in the championship on his day #swfc— Love length (@AtkinGeorge) 8 August 2017
Bannan was quality tonight hoping he will kick on now and flourish again #swfc— Devon Cash (@devon_cash12) 8 August 2017
I would drag my balls backwards over a mile of Scorpions and broken glass, just to sniff a cinema seat Barry Bannan once sat on #swfc— Cacky Raphael (@London_Calling_) 8 August 2017
Wednesday had trailed to a Kristian Dennis penalty scored late in the first half, but quickfire goals from Gary Hooper and Steven Fletcher had the Owls in front at the break.

And Bannan's strike all-but sealed the hosts' progress, before Sam Hutchinson's did exactly that.
How good was Bannan's display?
