A deflected injury-time strike denied Dundee United a memorable Europa League victory against Dinamo Moscow as the Russians twice fought back in an absorbing 2-2 encounter at Tannadice.
Keith Watson looked to have earned United the advantage in the first leg of the third qualifying round after he bundled home from close range - but Alexander Kokorin silenced the home crowd with a 25-yard strike that looped into the net off a United defender.
United had taken the lead against the run of play in the 37th minute when Willo Flood drove home from 16 yards and they created a series of chances before Igor Semshov headed the Russians level five minutes after the break. United debutant Radoslaw Cierzniak produced a string of excellent saves and Watson struck in the 75th minute.
United suffered narrow defeats to AEK Athens and Polish side Slask Wroclaw in their previous two campaigns and they have given themselves a fighting chance of going one better, although the second away goal leaves Dinamo favourites.
The Russians started brightly and were looking bigger, stronger and slicker on the ball and United survived several scares involving striker Kevin Kuranyi. The Germany international and Zvjezdan Misimovic got in each other's way after a cross caught out the home defence and the forward then miskicked and fell over after being played through.
Kuranyi produced a better effort from Marko Lomic's cross but headed just wide. United had not threatened Anton Shunin before the goalkeeper was picking the ball out of his net. John Rankin's shot deflected off a defender's heel and fell perfectly for the unmarked Flood, who drove the ball in off the far post.
United had the first chance of the second half after a corner when Sean Dillon blazed over when a ball across the face of goal might have set up a team-mate. But the visitors levelled after left-back Lomic made an untracked overlap.
The defender's cross cleared the goalmouth but the ball was chipped back in by Kokorin and Semshov stooped to head home from six yards after getting in front of Gavin Gunning's attempted clearance.
Tannadice erupted when some persistence paid off following Mackay-Steven's corner. Shunin saved Gunning's header and Watson converted from close range after Daly's effort was blocked.
United kept the pressure on before dropping back and looked to have survived after Kokorin's shot hit the outside of the post from a tight angle. But the striker was celebrating two minutes into injury-time after a long ball fell for him 25 yards out. The front player's left-foot strike hit a United defender and looped over Cierzniak and into the top corner.
