Manchester City closed the gap on leaders Manchester United in the Premier League title race as Gareth Barry scored a late winner to sink Reading 1-0.
Barry scored in the dying minutes to earn three points at Etihad Stadium as the champions struggled to find a way past a dogged Royals team.
Reading have the leakiest defence in the Premier League, but neither Sergio Aguero nor Carlos Tevez could make the home side's dominance count, while Barry's header was fired straight at Adam Federici.
The visitors stuck to their game plan, often playing with eight at the back and camped in their own half for most of the match.
They looked to have done enough to earn a point and stem a run of six successive defeats, but suffered a heartbreaking defeat after Barry nodded David Silva's cross into the bottom corner.

It was not vintage Arsenal in dire weather, but they kept plugging away and a Mikel Arteta penalty on 59 minutes after Theo Walcott had been felled in the box by Jean Beausejour sealed the three points.
The result leaves Arsenal in third by virtue of their goal difference, with Tottenham having missed the chance to move into third as they were held to a 0-0 draw by Stoke City at White Hart Lane.

Downing then scored his first Premier League goal for Liverpool, beating former Reds defender John Arne Riise before rifling in a powerful strike from the edge of the penalty area. Luis Suarez put the icing on the cake with a fourth in injury time as Liverpool moved up to eighth.

Leon Osman's header found the back of the net from a corner, but referee Anthony Taylor deemed that Victor Anichebe had impeded Hammers 'keeper Jussi Jaaskelainen. Carlton Cole added insult to injury just two minutes later, turning neatly to beat the Everton defence to smash the ball past Tim Howard from the edge of the area.
But Everton made a bright start to second half and were rewarded for their pressure, with Victor Anichebe rising to meet Pienaar's whipped cross to draw Everton level.
Sam Allardyce was left fuming when Cole was given his marching orders after he caught Leighton Baines with his studs with the scores still level, and the sending off proved costly as Everton made the most of their numerical advantage, Pienaar bundling home from close range after some neat play from Osman.
Gibson was sent off in the dying minutes for a high challenge on Mark Noble, but Everton held on for three points.

Snodgrass, who had been fouled by Peter Odemwingie from 25 yards, curled a superb effort into the top corner for his third goal in five games, but the Baggies bounced back, Gera knocking in from close range after Mark Bunn could only push Jonas Olsson's header onto the bar.
