Kilbane told the Daily Star: “David and Sunderland are the perfect fit. But everyone has to be realistic. There were difficulties in the transfer market which stemmed from David getting the job so late. He wasn't able to get his No.1 targets.
“So those he has ended up with are not established Premier League players and not the signings he'd have wanted to make long-term.
“Sunderland need continuity. David can give them that – providing they stick by him."
