It looked like the home side were going to take an early lead when Arsenal won a penalty less than 10 minutes in after Sanchez was brought down by Armand Traore.

However, Sanchez's spot kick lacked power, leaving Rob Green with a comfortable stop to his left, keeping the sides level.

The Gunners got a free kick from a dangerous position with just under half an hour gone, but Green got across to palm Olivier Giroud's curling effort clear.

QPR started to see more of the ball as the half progressed, but the hosts broke the deadlock shortly before the break when Kieran Gibbs crossed the ball in for Sanchez to head past Green.

Steve Caulker almost got the visitors, who have no points away from home so far this season, back on level terms, but his header was just wide after he fought his way past Per Mertesacker.
