LONDON — Alexis Sanchez scored one goal and set up another to make up for a moment of madness from teammate Olivier Giroud and help Arsenal beat Queens Park Rangers 2-1 in the Premier League on Friday.
Sanchez had a penalty saved in the ninth minute but responded by heading Arsenal ahead in the 37th from Kieran Gibbs' cross.
France striker Giroud received a straight red card in the 53rd for head-butting QPR defender Nedum Onuoha in front of the referee.
Yet Arsenal doubled its lead when Sanchez went on a winding run before laying the ball off for Tomas Rosicky to side-foot home from inside the area.
Charlie Austin smashed a penalty down the middle of the goal in the 79th to set up a frantic finish, but Arsenal held on.
