Scotland scored 21 league goals for the Swans least season, earning him a move to the Premier League side.
However, Pintado believes he has the potential to lead the forward line and told Wales Online: "I want to fulfil my potential and I'm working really hard towards that.
"I've always felt I can play well in British football because it suits my style of play. I want to prove that this year.
"I don't feel any extra pressure now Jason has gone. I had the same pressure when he was here, but now I have to work hard every day to score more goals."
