Sunderland have already brought one new player to the Stadium of Light this month in the form of defender Jimmy Dunne.
Sunderland have made one addition so far this month, with Jimmy Dunne arriving to strengthen the Black Cats’ defence.
Ross is still looking for new signings, as he aims to bolster his options at the Stadium of Light.
But Sunderland are not on the verge of completing any business before their next game against Scunthorpe United.
He said: “I have always been quite straight-forward and when I knew somebody was coming in then I would say I expect it to be the case, but I can’t say anything definitely that somebody would be in for (Saturday’s game at Scunthorpe United).”
Sunderland are thought to have funds to spend in January, as they aim to seal an automatic promotion space.
Ross’s side are currently in third place in the League One table, and missed an opportunity to break into the top two at the weekend.
Sunderland could only manage a 1-1 draw against Luton Town, after they gave away a penalty in the second half.
Sunderland are next in action against Scunthorpe United on Saturday, when new addition Dunne could be handed a chance to start.
