Cazorla comes to Arsenal's rescue with stoppage-time penalty (The Associated Press)

Arsenal relied on Santi Cazorla's stoppage-time penalty to secure a 2-1 victory over Southampton on Saturday after another unconvincing display from the London club as it chases a first Premier League title since 2004. Faced with dropping another two points, Arsenal benefited from a favorable refereeing decision after Jose Fonte dragged down Olivier Giroud with a tug on the striker's shirt 30 seconds into stoppage time. It was Giroud's most significant contribution in the half hour after replacing Lucas Perez, who was similarly ineffective up front on his debut.
