The Black Cats lost 5-1 at St James' Park in the first of two fixtures, while a last-minute Asamoah Gyan equaliser in January spared blushes in the return.

"We were much more inexperienced, and the lads who played last year have learned from it.
"Obviously, it's going to be talked about, we got a drubbing at St James', but leading up to that game we were playing really well.
"We were so consistent, we were on a run of 10 games unbeaten, sixth in the league, playing the best football, and were so confident and I think we maybe underestimated them in the first game.
