Ronald Koeman has said that he is expecting a "more difficult" game against West Ham United tomorrow than when his Southampton side faced the Hammers at the start of the season.
The Saints won 3-1 at Upton Park earlier in the season, but Sam Allardyce's side have lost just once in their last five outings, and drew with Manchester United at the weekend.
The manager told the club's YouTube channel: "They played a great game last weekend against Manchester United. They deserved more than one point.
"It will be a difficult one but we will try and we would like to bring the points to our fans on Wednesday night. I really like the West Ham United team and how they are doing this season.
"West Ham, we know, is a totally different team than in the beginning of the season when we beat them in the away game. It will be more difficult than that on Wednesday."
The teams meet at St Mary's tomorrow evening.
