18th-placed Swansea face 17th-placed Southampton in a huge Premier League relegation clash at the Liberty Stadium.
Both sides are on 33 points and know that a win can give their survival bid an almighty boost.
A win for either side tonight will also see West Brom's relegation confirmed.
However, it will still be all to play for for the Swans and the Saints, who face Stoke and Manchester City at home respectively in the final weekend of the league on Sunday.
So how do both sides line-up for one of the biggest games of the 2017/18 season?
