Everton boss Roberto Martinez says they paid for a lack of a cutting edge for defeat to Sunderland.

Everton had scored in their previous seven league matches but a first home defeat of 2015 was frustrating for Martinez.

"You have to score goals. I would have been very disappointed if we had not found the way to have an attacking threat or it had been a pedestrian game," he said.

"I don't think today has been that case but we cannot be happy with what happened in the 18-yard box.

"I don't think we were sharp enough. We had 22 attempts, 15 corners, 75 per cent possession.

"The technical aspect of the performance was very good and I thought we opened Sunderland up in many occasions.

"Today everything that could have gone against us in our box did - like a deflected shot the first time they got anywhere near our 18-yard box.

"The two goals are very unfortunate, the second John Stones gets impeded by Steven Fletcher."
