Swansea can climb out of the Premier League relegation zone if they avoid defeat to West Ham and other results go their way in their crucial encounter at the Liberty Stadium.
Both teams go into the contest having lost their last game in the league 4-1, with Swansea losing at Brighton, while West Ham were defeated by Liverpool at Anfield.
New Hammers boss David Moyes has steadied the ship but he will be keen to get a result as his side are only three points above the drop.
So how do both sides line up?
