Burnley 0-1 Arsenal Highlights (Koscielny with controversial winner for Arsenal) #BFCvAFC

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 onto 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 at 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.

Handball or not?

Immediately after the match, Koscielny - who was credited with the goal - said he did not know whether he had handled. "I tried with my right foot and I don't know if I touch it with my hand," said the Frenchman.

Even though Burnley did not appeal for handball at the time, their manager Sean Dyche said afterwards that the ball "quite clearly" hit the defender's hand.

To add to the confusion Arsenal's winner caused, Oxlade-Chamberlain celebrated as if he had scored but the England international's shot did appear to hit Koscielny's arm before it crossed the line, while Dyche even suggested that it was the Arsenal captain who kicked the ball onto his own arm.

As another caveat, if it were the case that Oxlade-Chamberlain did kick the ball onto Koscielny's arm, the defender would have been in an offside position.

But no matter what the theories, referee Craig Pawson saw nothing wrong with the winner which secured Arsenal a fifth successive Premier League win and ensured another win for Wenger as the 21st year of the 66-year-old's reign began.
