Sunderland are said to be looking to bring in two new players in the January transfer window.
Sunderland may have won six matches on the bounce, but Ross still wants to add quality to his squad.
The Black Cats are currently sat in the automatic promotion spaces, but the Wearsiders are refusing to rest on their laurels.
Indeed, Ross has been locked in discussions with Sunderland transfer chief Tony Coton recently, with plans being put in place.
Ross is said to want to add another two players to his squad, to bolster his options even further.
Sunderland are believed to have their eyes on striker Lawrence Shankland, who Ross knows from his time in Scotland.
Sunderland are next in action in the FA Cup at the weekend, when they take on Port Vale.
