The 28-year-old striker scored the only goal of the game as Spurs beat Swansea 1-0 at White Hart Lane on Sunday, continuing their perfect record in the Premier League after two games.

"The first few games I think are the hardest of the season and we have played well, but we can still improve a lot," Soldado told The Telegraph.
"I think this is quite a strong squad and a competitive team and that can only be a good thing for us.
"To hear the fans signing your name is special. Maybe the physical aspect of the game is the biggest difference from La Liga – the referees here allow much more contact and the games are a lot quicker. This is something that I have been taking in bit by bit."
Next up for Soldado and Spurs is a trip to arch rivals Arsenal, and the former Valencia striker is eager to grab his first taste of a north London derby.
"It’s the most beautiful derby, the one with the biggest rivalry for Tottenham and I cannot wait to play in this environment," added Soldado.
"There are rivalries in La Liga, just as there are here in the Premier League. Tottenham against Arsenal is one of the most beautiful games for the club and everyone who has come in from outside will want to play in it."
