Sunderland midfielder Jack Colback admits their thrashing at West Bromwich Albion was a shock.

Colback is hoping his side can put the memories of defeat at the Hawthorns behind them with a bounce-back showing on Tyneside.

"It was a disappointing one at West Brom, especially as we went down there with a lot of confidence and hoping to get another win," he told safc.com.

"West Brom set themselves up well and for all that we didn't play well, they put in a good performance and definitely deserved the win.

"The early goal was key, as it always is when playing at home. The fans got right behind them and we didn't recover. We didn't turn up, really.

"The nature of this league is that you're not going to win every game.

"We've turned teams over before and they have bounced back; now that's something we need to do."
