John O'Shea has warned his Sunderland team-mates last season's heroics against Manchester City will count for nothing this time around.
The Black Cats beat City 1-0 at the Stadium of Light on New Year's Day when substitute Ji Dong-won struck at the death after Martin O'Neill's patched-up side had survived something of a mauling.
The former Manchester United defender, who helped his side to a first league win of the season against Wigan last weekend, said: "It's a totally different situation. City have added to their squad, we have added to our squad and made some changes along the way."
