The midfielder says he used previous experience of scoring past Brad Guzan to net his free-kick on Saturday.
The Icelandic midfielder struck a curling free kick into the top corner past Brad Guzan to level the scores at Villa Park after Jordan Ayew had given the host the lead.
Andre Ayew then scored an 87th minute winner for the side to see them to a 2-1 victory and end a run of five games without a win for Garry Monk’s side.
And Sigurdsson was delighted to secure all three points, saying the result was a massive one for them as they showed fantastic character to come from behind.
“It was a massive three points for us,” he told swanseacity.net.
“It was difficult especially after we went 1-0 down and the crowd were really behind them, but we managed to turn the game around and dig out a win. We showed fantastic character”.
The midfielder also says that his previous set piece goal against Guzan ten months ago played its part in his goal this time around.
The last time Sigurdsson scored a free kick was in that game against the Villains at the Liberty Stadium last season, as he curled a free kick past a helpless Guzan on that occasion as well.
And he says he remembered what the American did last time and so aimed for the corner knowing it had a good chance of ending up in the back of the net.
“It’s been a while since I last scored a free-kick – the last one was against Villa last December,” he added.
“I didn’t think the keeper would move – I watched what he did for the last time I scored against him, so that played a part in which corner I went for. They had a few big guys in the wall, but I connected well and once it was over the wall I knew it was in.”
