Sunderland caretaker boss Eric Black believes new manager Martin O'Neill will start to revive the club's fortunes.
O'Neill was in the stands to watch the Black Cats blow a 1-0 lead to lose 2-1 to Wolves.
Black said: "Martin will have seen the strengths that we have. I think he knows there are some good things to take forward.
"But I think he'll also know that there are some problems. I'm sure he'll start on Tuesday trying to rectify those problems.
"I'm sure he'll be able to start turning things around."
