Union get forward well and Ilić finds himself in the box before squaring to the unmarked Skarke, who drills a superb shot into the bottom-left corner.
Will Werner, making just his second Bundesliga appearance of the season, help Leipzig snatch a draw?
After Union clear a Leipzig corner, the hosts pour forward down the right through Skarke. Much like Schäfer moments earlier, he sprints into the box but can only drill a low shot from an acute angle at Gulácsi.
The Union midfielder wins the ball wide on the right and drives into the box. He doesn't have much choice but to shoot from a tight angle but his vicious drive his pawed away by Gulácsi.
The visitors are camped out inside the Union half right now as they push for an equaliser. Union look comfortable in defence though, and have managed to keep them away from goal.
Leipzig have won all six of their Bundesliga home games this season but are on course to lose a third away fixture, if this scoreline holds.
The visitors were statistical favourites to win at kick-off, but their odds have sunk to just five percent now.

Union bring on some fresh legs, but the newcomers are attackers too; they're not just going to defend their lead now.
Three goals in seven minutes! Trimmel is afforded way too much space wide on the right. He delivers an inviting cross into the box and finds Ansah, who ghosts past Nedeljkovic and heads in from the edge of the six-yard box.
Diomande sprints forward, outpacing three defenders. He gets into the box but is stopped in his tracks by Köhn.
Fantastic skill from Diomande there as he wins the ball and holds off the challenges of three Union players before sprinting forward into space. Doekhi stops him the only way he can - by pulling his shirt.
The second half has started in much the same way as the first was played: lots of tackles.
Union get the second half underway. No changes at the break from either side.
Ansah's cross from the left goes all the way through to the back post. Haberer seemingly wasn't expecting it though, and contorts his body between a header and a volley - and ends up bundling the ball just wide with his knee. That could have been the opener!
Leipzig struggle to clear a high, looping free-kick into their penalty area. It's only cleared as far as the edge of the area, where Kemlein is arriving. He strikes the ball first time with his left foot, but it flies just wide of the upright,
Raum curls one over the wall but it doesn't dip enough and it sails just over.
Diomande gets brought down right on the outside of the Union box. Free-kick for the visitors in a dangerous location...
The match hasn't been quite as easy on the eye in the last few minutes, with plenty of little niggly fouls disrupting the flow.
Diomande has won more duels than any other player on the pitch so far. As good as he is going forward, he's just as happy to do the hard work in defence as well.

From the ensuing corner, Baumgartner gets his head on the ball and powers it at goal - but Rønnow produces another brilliant save!
The Leipzig attacker dribbles past a couple of defenders on the left-hand side of the box and smashes a shot goalwards, but Rønnow dives down well to his left to keep it out.
The visitors have attempted more passes (133 to 56) and completed a greater percentage of them than Union too (89% to 76%).

Diomande receives the ball wide on the left and passes back to Raum. His attempted cross into the box goes over everyone though.
The best chance of the half so far as Jeong gets to the ball just before Orbán and suddenly has space to attack. He has options to his left but instead opts to shoot. It looks like a rushed decision as slices way off target - he could have advanced a lot closer to goal there.
The forward receives the ball in plenty of space towards the right side of the penalty area. He could pass or try to shoot with his left foot, but instead tries to take on a defender on the outside, but runs out of space and it goes out for a goal kick.
Leipzig are trying to get through Union's compact defence with some swift one-touch play around the edge of their penalty area. It hasn't worked out just yet, but they've strung some nice moves together and if they keep at it, you suspect they'll get through sooner or later.
Anyone expecting Union to just sit back and wait for openings on the counter or from set pieces is well wide of the mark here. Both teams are going on the front foot whenever they can. It's been frenetic and end-to-end already, albeit without any sights of goal.
