There is an extremely good chance that Chelsea go the remainder of the season unbeaten. The bookies generally have Chelsea winning the league 75% of the time and their remaining fixture against Man City is in London which makes a big difference to the season run in.
The only concern is if Chelsea open a 10 point gap on Man City and there is an important semifinal Champions League match where we rest a few players in the PL and get hit by Arsenal on the 25th April.
