Sunderland were something of a surprise package last season as they won promotion to the Premier League via the Championship play-offs, but that hasn't stopped them investing heavily in their squad in anticipation of their first season back in the top flight since 2016-17. Enzo Le Fee's loan move has been made permanent, while Habib Diarra, Noah Sadiki, Reinildo Mandava, Chemsdine Talbi and Simon Adingra have all arrived at the Stadium of Light.
