Southampton manager Ronald Koeman has urged his side to attack Manchester United when the sides meet at St Mary's Stadium.
The Saints have scored just two Premier League goals this season but Koeman believes that his team can cause problems for the United defence.
The Dutchman told the club's website: "It's a good game to show that we can play attacking football and create chances.
"We have to be confident. If we are not you can't win. You have to show your qualities and your belief in a good result on Sunday.
"They are a big team, a big club. A lot of attention comes to everybody. That makes the game more interesting. I think that's the best word for Sunday."
Southampton look for their second win of the season as they host Manchester United on Sunday afternoon.
