Sunderland aren't even in the Premier League — they're in the Championship — so this matchup doesn't exist at the top flight level right now.
That said, if you want a prediction based on those records as given:
Forest's 9-9-15 record tells the whole story — they're a side that loses too often to feel safe at home. Sunderland's 12-10-11 shows more consistency, but 11 losses isn't exactly inspiring either.
Key matchup: Watch Sunderland's midfield try to control tempo against a Forest side that'll sit deep and hit on the counter.
Forest have won just 9 of 33, which means backing them at home is a stretch. Sunderland's superior win rate makes them the pick here.
Prediction: Sunderland win 2-1, nicking it late after Forest inevitably push forward chasing an equalizer and leave gaps at the back.
