Arsenal have a four-point lead at the top of the Premier League table. They're frontrunners and according to the numbers, they're the favourites. But how many points are needed to win the title this season?

The Opta supercomputer has given Arsenal a 66-per-cent chance of winning the Premier League - and for good reason. Because opposition teams are really struggling to get close to them.

Arsenal have pulled off eight wins in a row in all competitions - winning the last six without conceding a goal. The Gunners have only conceded twice since the September international break - while only Erling Haaland has managed to score from open play against this Arsenal defence all season.
