Burnley suffered a cruel defeat at Turf Moor as Arsenal secured victory with a controversial Laurent Koscielny goal in the final act of an intriguing match.
In added time, Theo Walcott headed across goal towards Alex Oxlade-Chamberlain whose effort went in off what appeared to be Koscielny’s elbow.
As well as a possible handball, there was also a hint of offside with captain Koscielny standing on the goalline.
Michael Keane had Burnley’s best chance, heading on to the crossbar.
But despite the Clarets’ fine defensive display, with Keane in particular impressing as they shut out Arsenal until the 94th minute, they came away with no points for their efforts.
The win allowed Arsenal to close the gap on league leaders Manchester City, who lost 2-0 Tottenham in one of Sunday’s earlier kick-offs, to two points while overtaking Liverpool to claim third place.
Manager Arsene Wenger admitted his team were fortunate in victory but with this result at Turf Moor, and convincing victories over Chelsea in the league and Basel in the Champions League in the last week, the north Londoners have hit a fine run of form, extending their unbeaten stretch to six league games.
