The Easter Road club have yet to find form and have lost pre-season matches against Barcelona, Cowdenbeath and Clyde, while they struggled to a goalless draw against Raith Rovers.
Paatelainen says he is keen to add some firepower to his squad but will have to watch the two games following the SPL opener at Rugby Park from the stand.
Speaking on Wednesday, he said: "I want to bolster the striking department. We haven't scored too many goals.
"Am I worried? No, because we have goalscorers in the side. I know we will score goals, there's no question about that.
"We have players who create chances and we have players who score goals, no problem."
