Chelsea winger Eden Hazard believes Arsenal and Manchester United will be the Blues' biggest Premier League title rivals this season.
After playing to 1-1 draw with Liverpool on Tuesday, Chelsea sit on top of the league table, nine points ahead of the Gunners, who they meet at home on Saturday, and Tottenham Hotspur after 23 games.
The Red Devils are in sixth position, recovering from a slow start to the season to sit on 41 points from 22 games, ahead of their clash against Hull City at Old Trafford on Wednesday.
Hazard told Sky Sports: "I think Arsenal and Manchester United [are the biggest title rivals].
"United had a bad first part of the season and I think for a couple of games now, they played well.
"They drew against Stoke, but they have good players and the squad is very good. The manager is good, so they will be second or third.
"Tottenham also are strong. We lost there, but for me it is more Manchester United. They are more experienced. That is my opinion, maybe I'm wrong."
