"We had chances to win more comprehensively but towards the end we got a little bit nervous only because we obviously had a really hard game on Thursday.
"Some of the guys were cramping up so we needed to make changes. Sunderland were always going to throw balls into our box and hope something would drop for them.
"Overall we're delighted with the win. That's six home wins on the bounce so we're delighted after a good result in terms of getting into the next round in Europe and then a win against a spirited Sunderland side."
