Metalist Kharkiv overcame the first-half dismissal of Jonathan Cristaldo to hammer Malmo 4-1 and move to the top of Europa League Group G.
Jiloan Hamad had fired the home side in front, only for Cristaldo to equalise.
The Argentinian striker was then given his marching orders just five minutes after scoring, but the Ukrainian club responded magnificently with strikes from Vinicius Fininho, Edmar and Marko Devic wrapping up a comprehensive win.
Metalist travelled to Sweden with four points from their opening two group matches, while Malmo were yet to get off the mark following defeats to AZ Alkmaar and Austria Vienna.
But the hosts made a promising start and gave their opponents something to think about after five minutes with Wilton Figueiredo's 20-yard drive which flew past the right post.
Miljan Matuzadvic had another opening for Malmo seven minutes later but also fired wide, before Metalist midfielder Jose Sosa brought a save out of home goalkeeper Johan Dahlin with the visitors' first chance.
The Swedish club were looking the stronger, though, and it was no surprise when they took the lead after 22 minutes. Math Ranegie directed a free-kick into the area, where Hamad was waiting to turn the ball in from 10 yards.
Sosa tried to get Metalist back into the match, but could only put his right-footed strike on the half-hour mark over the bar.
The Argentinian did set up their equaliser two minutes later, though, curling in a cross which was headed home from close range by Cristaldo.
However, the goalscorer then suffered a rush of blood to his head seven minutes before the interval, with a crude challenge on Pontus Jansson which earned him a red card.
Yet Metalist overcame their numerical disadvantage and went ahead on the stroke of half-time, with Fininho heading in a cross from the right from Cristian Villagra.
Malmo were unfortunate not to be level 10 minutes in to the second half when Jansson's header from a Figueiredo corner came crashing back off the bar.
And Metalist took advantage by adding a third goal within two minutes. Xavier swung a corner into the area to find an unmarked Edmar, who poked home from six yards out.
The rout was then completed in the 74th minute by Devic, who picked out the bottom right corner from 12 yards with his right-footed drive.
