Chelsea are also bang in form, have no European games, and play Boro, West Brom, Sunderland, Stoke, Palace and Bournemouth before 2017. I'd be very surprised if Liverpool can keep this going all season as well, they're relying on a smallish squad, playing at a very high intensity, look at Spurs last year.
Also, as good as Liverpool are, Chelsea have Hazard who is the best player in the league on his day. Liverpool don't have a player of his quality, although Coutinho isn't bad!
