Swansea City have won their first match of the summer with a comfortable 4-0 victory at Plymouth Argyle.

The Premier League team took the lead with just nine minutes played when Rory Donnelly rolled the ball into an empty net following a mistake from the goalkeeper.

Their advantage was then doubled on 69 minutes thanks to Jordi Amat's instinctive finish from close range.

The Swans made it 3-0 three minutes later as the returning Gylfi Sigurdsson calmly slotted in after being picked out by youngster Alex Bray.

A fourth goal for the visitors came deep in added time when Sigurdsson bagged his second of the match with a fine free kick that curled into the top corner.

Garry Monk's side continue their pre-season campaign on Tuesday when they make the trip to Exeter City.
