Swansea City beat Watford 1-0 at the Liberty Stadium to move back out of the relegation zone in the Premier League on Monday.
Ashley Williams opened the scoring midway through the first half, and his strike proved decisive in a game of few chances.
After an energetic start, the two sides produced a fairly tedious encounter as Watford failed to trouble their hosts, who were largely content to sit back on their lead.
Over the weekend, Manchester United beat Liverpool 1-0 in a smash-and-grab win at Anfield, while a goalless draw with Stoke City was enough for Arsenal to retain their position at the top of the league thanks to Leicester City's stalemate with Aston Villa.
