"When you look at the game today, twice we had situations - once when 1-0 down and then when they came back to 2-2 - where we had to find the resources to win the game".
Southampton: Alex McCarthy 7, Cedric Soares 7, Maya Yoshida 6, Jack Stephens 5, Wesley Hoedt 6, Ryan Bertrand 6, Oriol Romeu 6, Pierre-Emile Hojbjerg 7, James Ward-Prowse 7, Dusan Tadic 5, Shane Long 7.
Despite today's scoreline, Arsenal have struggled in the Premier League this year, with the club now occupying 6th spot in the table.
The game ended on a sour note when both teams had players sent off, as Jack Stephens and Mohamed Elneny were given straight red cards for off-the-ball incidents.

Arsenal levelled just before the half-hour mark when Welbeck's clever flick allowed Pierre-Emerick Aubameyang to scuff the ball past the onrushing Alex McCarthy.
The Saints were level in the second half thanks to super sub Charlie Austin, but Welbeck headed in the victor for the hosts.
The Frenchman has also underwhelmed this season and has only scored 10 times in 27 games; disappointing when you consider how prolific he was for Lyon in Ligue 1 last season.
The home side soon found themselves in front as Welbeck scored his first league goal since September.
"I'm happy with the assist, glad to get the goals".
"I am very pleased for him because he is a guy who went through a very hard time and has shown exceptional mental strength to come back", said Wenger.
"I thought I would get another opportunity to get a victor and I kept focused on that".
