Arsenal marked Arsene Wenger's 20-year anniversary with a last-gasp winner to beat Burnley 1-0 and claim all three Premier League points.
Laurent Koscielny ensured Arsene Wenger marked his 20-year anniversary at Arsenal with a victory as he scored a controversial late winner to beat Burnley 1-0 at Turf Moor.
A resilient display from Burnley was undone in the final minute of stoppage time as Alex Oxlade-Chamberlain and Koscielny fumbled the ball over the line – despite the latter appearing to handle while also being in an offside position.
Chances were at a premium on Sunday, a day after Wenger brought up his two-decade landmark in the Gunners' hotseat, with Alexis Sanchez wasting the visitors' best chances.
