Southampton are winless in their last 11 matches, losing nine of them.
Swansea have only lost two of their last ten games.
Swansea have won 2-1 in two of their last five away fixtures.
Swans can pile misery on Southampton
Southampton are odds-on to beat Championship side Swansea on Sunday, but the visitors could spring a surprise against the struggling Saints.
The hosts have been cut adrift at the bottom of the Premier League table, earning just six points from 20 games and already ten from safety, and they enter the FA Cup off the back of an 11-game winless run.
Morale will be at an all-time low on the south coast, and that is something Swansea can take advantage of.
The Swans have lost just two of their last ten matches and look good value in the double chance market, while 2-1 wins over Derby and Plymouth in their last five away games make that an appealing correct score prediction.
