Southampton v Swansea: Sutton's prediction

BBC Sport football expert Chris Sutton has made his predictions for all 32 FA Cup third round games and given his verdict on who will make it into round four.

For this week's matches he is up against actor and musician Billy Bob Thornton, who is a Liverpool fan.

Sutton's prediction: 3-2 after extra time

The fan at St Mary's last weekend who said Southampton would lose 5-0 to Brentford should really replace me and do these predictions.

This tie is a lot harder to call, though. You could call it the Russell Martin derby, because he managed both teams, but I am not sure either side play like they did when he was in charge.

Saints boss Ivan Juric has got to pick a strong side after what happened against the Bees, and his aim must be to find a team that starts to find some rhythm again.

I do think Southampton will edge this, because they have to, but what a miserable existence it has been for their fans this season. Maybe the FA Cup will give them something to cheer about?

Billy's prediction: 1-0
