Jonjo Shelvey was adjudged to have fouled Andros Townsend, but although the offense appeared to take place inside the Swansea penalty area, referee Neil Swarbrick awarded a free-kick.
However, when the same players came together in the second half, Swarbrick did point to the spot and Spain international striker Soldado kept his cool to convert his second Premier League penalty in two games.
It was Spurs’ second win of the campaign, following their 1-0 success at Crystal Palace, and it took them level with Chelsea and Liverpool at the top of the fledgling standings ahead of Chelsea’s trip to Manchester United yesterday.
“It’s a good start. Last season we had a different start to the season,” said Spurs manager Andre Villas-Boas, whose faces archrivals Arsenal next weekend. “It gives us a little bit of confidence heading into a difficult game against Arsenal next week. I’m very pleased.”
