The Swans started their Premier League campaign with a surprise 2-1 win at Manchester United on Saturday.
Despite seeing his team earn an impressive victory on the opening day of the season, Monk remains eager to boost his squad in the coming weeks.
"We're trying to work on certain areas to bring two or three bodies in which we really do need," he is quoted as saying by BBC Sport.
"We need to add two or three players to boost the squad in terms of numbers and quality and that's what we'll be looking to do."
Swansea have signed eight new players so far this summer, including goalkeeper Lukasz Fabianski from Arsenal.
