Wenger blames bad luck and referee error for Arsenal rout

Arsene Wenger acknowledged Southampton were the sharper team as they crushed Arsenal 4-0 on Saturday but he also blamed the defeat on bad luck and a second goal that should have been disallowed by referee Jonathan Moss. Cuco Martina opened the scoring with a curling long-range effort. Shane Long then added the second goal when the Ireland striker fouled Arsenal defender Laurent Koscielny outside the box before getting on the end of Sadio Mane's right-wing cross.
