Chelsea are currently sitting third in the league after collecting 39 points and with16 points behind the leaders no chance for them to hold the title this season and they can only fight with United over runner's up because for now they are safe to finish in top 4
I think the other positions are still open to a challenge and I would not say Chelsea are far from safety because Tottenham, Liverpool ,Arsenal, Burnley, Leicester are all fighting for this place.
and in the latest game they have created 26 scoring chances but they didn't convert any with them having good defense but a small squad Conte cannot make enough changes for rotations as his players would be tired now around Christmas. While visitors Brighton have a good defense and sitting at a safe spot at the middle . I expect from this game to see just few goals scored because Morata is not in form also Brighton is good at back.
December games are an endurance test for most teams and I think Chelsea has a lot of experience to call it fatigue this time around, they will be more than ready to take on Brighton and challenge ManU for the second position...am expecting another hat trick to be scored today.
