Chelsea are currently two points behind their North London rivals, and are nowhere near Arsenal's level in attack thus far, scoring 13 goals less!

With Man United getting their season back on track last night with a 2-1 win over Liverpool, Ljungberg reckons they will prove to be Arsenal's biggest rivals this season.

He told World Soccer magazine: "Chelsea have bought a lot of great players, they have a new manager in charge and look to have the strength in depth to win it.

"However, I still see Manchester United as our biggest threat. United have the experience of winning the league; Chelsea don't yet. They are bringing in players from abroad and it may take time for them to settle.

"Jose has a much bigger squad than we do, so it will not be easy for him to keep everyone happy."
