The Swans raced ahead with just two minutes on the clock courtesy of Nathan Dyer's well-taken effort, and Wayne Routledge added his side's second with a fine strike on the 24-minute mark.

Dyer rounded off the scoring with his second 20 minutes from time to leave the Swans sitting atop the Premier League after three games.

Was the result fair?

Absolutely. Swansea City were the dominant side from start to finish this afternoon, and the contest was as good as over by the interval. The hosts came into the game in fine form, and it took just two minutes for Dyer to get them up and running with his well-taken goal. A second followed soon after in some style, but it was more a question of when rather than if the Swans would add a third. West Brom failed to turn up, and it was not until the game was over at 3-0 that they began to test Lukasz Fabianski with some efforts on goal.

Swansea's performance

There is not many better sides in the division to watch than Swansea when they are at their free-flowing best, and that was the case for large parts of this afternoon. In truth they probably could have moved up another gear, but having found themselves two goals to the good so early on, Garry Monk's charges never really had to up their game. Gylfi Sigurdsson in particular looked hugely impressive in midfield, adding another couple of assists to his collection, while Dyer is surely knocking on the door for an England call-up with his second and third goals of the season today.

West Brom's performance

Coming into this clash in South Wales, it was hard to judge just how good or bad West Brom's start to the season had been. Unbeaten maybe, but last week's goalless draw against Southampton was a dire affair with chances lacking. It was not much better at the Liberty Stadium, with Alan Irvine now having two weeks to improve certain areas of his team. No side has made more signings that the Baggies this summer, and it will quite clearly take some time for the team to bed in and work together as one.

Sports Mole's man of the match

Gylfi Sigurdsson It is tough to pick out just one player for this accolade, particularly when Dyer bagged a double and Routledge scored a contender for goal of the season. But the man who makes it all happen is Sigurdsson, who sits in the hole slightly behind Wilfried Bony. He now has four assists in a Swans shirt this season, which is more than the Iceland international managed in 58 appearances for Tottenham Hotspur.

Biggest gaffe

It was a terrible start to the game for West Brom defender Jonas Olsson, whose slip after 87 seconds allowed Dyer to put the Swans ahead. The centre-back clearly felt that his boots were to blame, running down the tunnel soon after to change his footwear before returning and almost heading into his own net. One of those days.

Referee performance

Paul Tierney had a couple of penalty calls to make, and it looked as though he got both wrong. Olsson was dragged down by Ashley Williams in the first half, while Andre Wisdom looked to handle the ball on the line in the second, with neither decision being given.

What next?

Swansea: Following the two-week international break, Swansea travel to face Chelsea at Stamford Bridge in what could potentially be a meeting between the division's top two sides.

West Brom: The Baggies face a tough-looking fixture of their own, going in search of their first three points of the campaign at home to Everton.
