"But they are still there and we aren't enough points ahead to think that the league is over. We just have to make sure we keep playing the way we are.
"So far it's been a very good Christmas for us - two wins, six goals, only one conceded and we've gained two more points on Chelsea.
"Confidence is very high but we're aware that it's a long season and there are still many tough games ahead.
"So we know it's going to be difficult.
"It's good to be in front, it's good to be playing good football, but we have to make sure we stay focused and that nothing deflects us from our target.
"When Chelsea dropped those points against Reading it maybe added a bit more pressure on us, because we had to capitalise and make sure we won.
"We have to focus on ourselves. We're playing well, scoring a lot of goals and defending very well. We have to concentrate and make sure we get the points we deserve."
