New signing Manolo Gabbiadini is ft and available for selection, Claude Puel has confirmed.
Southampton have won their last two matches against West Ham; they last won three consecutively against them in April 1998.
West Ham are winless in their last seven away league matches against the Saints (D4 L3), last winning in Southampton in November 2000.
Fraser Forster has not conceded a Premier League goal against West Ham in 333 minutes of action, keeping three consecutive clean sheet in that time.
Andy Carroll has been directly involved in six goals in his last nine away PL matches (five goals, one assist).
Claude Puel: "Van Dijk will stay not available for many weeks, two or three months. I don’t know how many times he will stay out but it’s a problem."
Slaven Bilic: "I like the way Southampton play. They've had ups and downs and played a lot of games, and have had injuries and got new players."
