Southampton 2-0 Arsenal: Wenger rues 'two big mistakes'

Arsene Wenger says "two big mistakes" were the reason for Arsenal's 2-0 defeat away to Southampton.

The Gunners fell behind in the first half after Wojciech Szczesny raced from his goal to allow Sadio Mane to curl into an empty net from a narrow angle.

Saints' doubled their lead in the second period when Dusan Tadic poked in after another Szczesny mistake, as Wenger's side tasted defeat for the first time in five league outings.
