EPL: Liverpool suffers surprise defeat against Swansea

Liverpool's poor first-half display against Premier League bottom side Swansea City left manager Juergen Klopp angry and frustrated as they lost 1-0 at the Liberty Stadium on Monday.

Swansea went ahead five minutes before the break when an attempt to clear by Liverpool's 75 million pounds ($104.88 million) defender Virgil Van Dijk landed at the feet of Mawson who swept the ball home for his sixth league goal this season.

Van Dijk, playing in his first league game since signing from Southampton, had earlier flashed over a header from a first-half corner, while Mohamed Salah blazed the Dutch defender's lofted pass over the bar on the half-hour mark.

Liverpool upped the tempo in the second half, dominating possession and attacking from all angles, and Roberto Firmino saw his late header come back off the post, but Swansea managed to hold on for only their fifth league win of the season.

Liverpool had not lost in 18 games, having just ended the unbeaten league record of runaway leaders Manchester City, but they fluffed their lines in the face of some stout defending.

The loss leaves the Reds on 47 points, three behind Chelsea and six off Manchester United, with Tottenham Hotspur two points outside the top four after a draw at Southampton on Sunday.

Manchester City leads the way with 65 points from 24 games.
