Arsenal lost further ground in the Premier League title race as Fraser Forster produced a stunning display to earn Southampton a goalless draw at Emirates Stadium.
The Southampton goalkeeper made a string of fine saves to ensure Arsene Wenger’s side failed to score at home in the league for the fourth time this season and are now four games without a win in the top flight.
Mesut Ozil had three clear chances to break the deadlock in the first half as Arsenal struggled to break down a resolute Southampton defence.
Ozil was unable to find a way past Forster, though, and the England international was on hand again after the break to deny Olivier Giroud and Alexis Sanchez.
Southampton could have inflicted even more misery on the Gunners had Sadio Mane and Dusan Tadic done better with chances of their own.
The draw – combined with Tottenham’s win over Norwich City – sees Arsenal slip to fourth, five points adrift of leaders Leicester City, while Saints climb to seventh.
