Darren Pratley scored both goals in the 2-0 win at Hillsborough with Sousa calling for more goals from his midfielder.
"He has started to understand better and better to pick his moments to attack," Sousa said after the match.
"This is what we expect from him, and if he starts to do it more regularly he will not play in the Championship, he will play in the Premier League.
"It is important to score goals to win games. We are working hard for everyone to be ready to score and it's what I want to see. Everyone should score.
"We want to do things our way. "We want to be better, be competitive and fighting for the three points.
"We are very consistent but we know we can improve.
"It is important to win. They started well but we showed the responsibility and the personality I want to see.
"I am delighted because we know how to score and how to win and I am happy with the three points."
