Manchester United fullback Rafael is confident they won't suffer from complacency as they sit 12 points clear at the top of the table.

Rafael insists no-one is getting carried away with the advantage, but maintains that every victory and clean sheet continues to boost the players' confidence.

"We're pleased to not be conceding and keeping clean sheets. We want to keep that going and continue picking up points," he told manutd.com.

"The more clean sheets we keep the more it improves our confidence. That consistency really helps us. We know what happened last season and that every game is important. We just have to keep winning."
