to yellow cards today along with costa who is sidelined by injury, i wouldn't necessarily make them favourites against man utd and arsenal.
still favourites to win the league but it would be a tighter finish than it looks like right now. chelsea have been fortunate that their key players have been fit and available all season. but the corollary of this is that they look a little flat compared to the first half of the season when they were amazing.
this along with strong arsenal and man utd form makes the title contest more interesting than it was. but that is largely because it looked totally over a few weeks ago. and now at least there's a long shot opportunity in play.
