Southampton seal fine Arsenal win

Southampton's comprehensive 4-0 defeat of Arsenal at St Mary's denied the Gunners the opportunity to go top of the Premier League.

Cuco Martina's stunning 30-yard strike on his first league start got the Saints off to a flying start, while Jose Fonte, and a Shane Long brace were enough to secure victory for Ronald Koeman's team.

It could have been even worse for Arsenal. Virgil van Dijk had a header ruled out for offside, and Dusan Tadic's strike was saved by Cech.

This was Arsenal's heaviest Premier League defeat since a 6-0 away loss at Chelsea in March 2014.
