Sunderland boss Roy Keane admits his side learnt a valuable lesson after their 7-1 thumping against Everton.

The former Manchester United captain has explained that his side will now employ a change in mindset for their travels, starting with Saturday's trip to Stamford Bridge.

"Everton looked like they could score every time they went forward," he told the Sunderland Echo.

"That's what you get when you're playing against a good team and they are high on confidence.

"We had an innocence in our football and had something of the cavalier about, us which you just can't afford when you are away from home against a quality side.

"It was a valuable lesson and the most important lessons from that game were learnt by me.

"My way of thinking for a lot of games is to be positive and to get at teams. I try to think positively, in terms of our shape, players and positions.

"My attitude has always been to try go out and win, no matter who we are playing and whether we are home or away.

"I'll perhaps have to change my mindset a bit - certainly away from home. When we go to play against the better teams, we need to change our mindset slightly.

"Sometimes people think it is great when you play cavalier, attacking football but it's not so great when you are near the bottom of the league."
