Tom Hateley's stunning stoppage-time free-kick gave 10-man Motherwell the away goal their enterprise deserved as a narrow 2-1 defeat to Odense left them with every chance of progressing to the Europa League group stages.
The Danish side looked to have inflicted a fatal blow to Well's hopes after Peter Utaka caught them on the break in the 78th minute to add to Chris Sorensen's soft first-half opener.
Steve Jennings was then sent off but Hateley curled into the top corner from 25 yards with a retaken free-kick to send 500 travelling fans into delirium.
The goal was the least Motherwell deserved for an attacking display which saw them enjoy as much territory and possession as their hosts. Brown played the whole second half with three up front despite initially changing his formation to a 4-4-2 with Chris Humphrey on the left wing and John Sutton playing just off Jamie Murphy.
Motherwell's promising start was undone in the 31st minute. Hungarian referee Zsolt Szabo waved play on after Caca fell under Stevie Hammell's challenge but changed his mind after his assistant flagged.
Sorensen swung the free-kick from 30 yards out on the right towards the edge of the six-yard box but the ball went straight into the far corner.
Motherwell began the second half strongly and created several chances but twelve minutes from time, they were exposed when Utaka beat Stephen Craigan for pace to reach a forward pass and rounded Darren Randolph before lashing past three Motherwell players into the roof of the net
Ross Forbes had a free-kick saved before Jennings received a second booking three minutes from time when he caught Espen Ruud late. But the 10 men stunned their hosts deep in injury-time when Hateley curled a glorious 25-yard free-kick into the top corner.
Hateley's first effort, after Nick Blackman had been hauled down by Hans Henrik Andreasen, had gone straight into former Manchester United keeper Roy Carroll's hands.
But the midfielder was allowed to take another after the referee blew his whistle in the act of shooting amid some jostling in the box, and the Englishman took full advantage with virtually the last kick of the ball.
