Arsène Wenger has underlined the importance of Arsenal's visit to St Mary's if they are to qualify for the Champions League.
The 67-year-old insists his side have to pick up all three points tomorrow night, but admits he is well aware of the threat his fellow Frenchman Claude Puel’s side will pose.
“We have a big game on Wednesday,” started Wenger.
“Southampton are a good team. Collectively they play well. They keep possession of the ball and we need to recover and focus to win on Wednesday.
“We still have a chance mathematically and we need some help as well from teams around us.”
Arsenal head into the game off the back of a 2-0 victory over Manchester United, though they suffered defeat to Tottenham Hotspur the week before.
And Wenger was quick to stress just how important the victory over United was for his side.
“It was important to beat them because we lost at Tottenham - that didn’t happen many times,” he explained.
“We couldn't afford to lose today. In fact, we have recently won at Middlesbrough, we beat Manchester City in the cup, we won against Leicester and today.
“We had just one blip and I think it was a bit physical. But overall, we look a bit more stable.”
