The Spain international converted his third penalty of the season with just 10 minutes remaining to seal an uncomfortable 1-0 win after Ahmed Elmohamady had been adjudged to have handled Jan Vertonghen's cross.
The victory took Spurs back in to the top four and Soldado hailed all aspects of the side as they look to develop in to a squad capable of winning the league.
"We're doing well at the moment," he said.
"We had to keep up with the teams who won on Saturday and Chelsea won as well, so we had to keep up with them.
"Apart from the blip against West Ham I think we've done very well at the back recently to not have any goals scored against us and I think we've done well, we've won our game and we're moving forward."
