The Gunners have caught their Premier League rivals off guard with impressive consistency this season.
Mikel Arteta has insisted Arsenal aim to build on their current form after the World Cup break.
Arsenal went five points clear at the top of the table after beating Wolves 2-0 on Saturday. It marks the first time the Gunners lead the Premier League at Christmas since 2007.
Following a highly-inconsistent last season, Arsenal have shown great improvement since the start of the new campaign. But Arteta believes they need to use the upcoming break to reflect on their playing style.
“Nobody expected us to be where we are right now,” said the manager.
“I am more focused on our way of playing, our way of living together, the atmosphere we have around Colney and what we have generated with our supporters in our stadium.
“That is much more powerful. It’s great to be where we are, we are enjoying that moment. We have a big break, we have to reflect on what we are doing and we are very much prepared for what is to come after the World Cup.
“When a team is in the moment you want to carry on playing. It’s not possible so we have to use the time now in the best possible way.
“Our aim is to play better as a team every single day, to have better tools to do what we want to do on the pitch.”
