Saints have one of the best defensive records in the country this season.
"They have not conceded many goals. I'll have to get on the ball and find a solution to that. Of course they are a good team and good defenders, but I don't care about another team, I care about my team and if we play well we can beat them," Arnautovic told The Sentinel.
"It would be nice to get a win at home in front of our supporters. I think our fans are very good, they are always supporting us everywhere we go and I hope it's the same against Southampton."
