Everton midfielder Gareth Barry warned they cannot forget about the defensive side of the game after conceding a two goal lead in the eventual 6-2 success over Sunderland on Saturday.

Roberto Martinez's men have already conceded 15 in 11 games, which is joint second-worst among the Premier League's top 14 sides.

"We are enjoying the win but the experienced players know on another day you want to be a lot tighter," Barry said.

"It is important we don't get away from the fact there is a lot of confidence from the attacking flavour but throughout the week we will be working on that attacking-defending balance, because we don't want to be giving away too many chances like that.

"Their (first) goal changed the game. If we are going in (to half-time) at 2-0 we are really comfortable and the confidence is different and their attitude to the second half is different.

"There are a lot of lessons to be learned there as with 30 seconds to go we've got the ball in their half and all of a sudden it's in the back of our goal.

"We should be better than that and there is experience on the pitch to stop that happening, but fair play to the lads we bounced back from conceding the second and created a lot of chances."
