Striker Alex Greive believes fresh competition will force every Saints player to raise their game next season.
St Mirren boss Stephen Robinson has already added three new faces to his squad this summer, with winger Jonah Ayunga the latest to sign on the dotted line in Paisley last week.
He joins former Motherwell pair Trevor Carson and Mark O’Hara in joining the club, with Western Sydney Wanderers star midfielder Keanu Baccus also expected to join imminently after agreeing a pre-contract switch.
