Half-time: Arsenal 1 QPR 0

Alexis Sanchez atoned for a penalty miss by putting Arsenal ahead in a one-sided first half at the Emirates Stadium.

QPR had an early let-off when Sanchez’s woeful spot-kick was easily kept out by keeper Rob Green after Armand Traore, playing against his former club, had brought down the Arsenal man.

But Sanchez made no mistake eight minutes before half-time when he headed in after being found unmarked by Kieran Gibbs’ cross.

That lapse came after Rangers, beaten in all nine of their away matches this season, had defended well.

They reverted back to three central defenders, with Rio Ferdinand recalled to the starting line-up while Traore was given a chance to impress at left wing-back in the absence of the injured Yun Suk-Young.

Arsenal: Szczesny, Debuchy, Mertesacker, Monreal, Gibbs, Flamini, Cazorla, Rosicky, Alexis, Giroud, Welbeck.
Subs: Ospina, Chambers, Bellerin, Coquelin, Walcott, Podolski, Campbell.

QPR: Green; Onuoha, Ferdinand, Caulker, Isla, Henry, Mutch, Kranjcar, Traore, Vargas, Austin.
Subs: McCarthy, Hill, Phillips, Fer, Wright-Phillips, Hoilett, Zamora.
