LONDON: Danny Welbeck's second goal of the game gave Arsenal a 3-2 win on Sunday and cost Southampton a draw they would have deserved in their struggle against relegation from the Premier League.

Southampton's defeat kept them in the bottom three, three points behind Crystal Palace but with a game in hand.

Shane Long gave them the lead after 17 minutes, nipping in ahead of defender Shkodran Mustafi.

Arsenal equalised 11 minutes later through Pierre-Emerick Aubameyang, playing a one-two with Danny Welbeck.

Welbeck then cut inside onto Alex Iwobi's pass to give Arsene Wenger's side a barely-deserved halftime lead.

Substitute Charlie Austin equalised barely a minute after coming on but with nine minutes left Welbeck headed in Alex Iwobi's cross.

In a wild last few minutes Mohamed Elneny and Southampton's Jack Stephens were sent off in separate incidents.
