If this was April, I'd agree, but there's still a lot of matches to play. Chelsea also face Spurs and Liverpool at home, so they have a slight advantage head-to-head.
I wouldn't be surprised if Liverpool/Spurs finish third at the expense of Chelsea.
Thanks to Red Sky for this :
CL - Chelsea v Barcelona 20th Feb
PL - United v Chelsea 25th Feb
PL - City v Chelsea 4th Mar
PL - Chelsea v Palace 10th Mar
CL - Barcelona v Chelsea 14th Mar
PL - Burnley v Chelsea 17th Mar
PL - Chelsea v Tottenham 1st Apr
They could have an FA Cup fixture in there too if they beat Hull on the 16th Feb.
And to me for posting this earlier (Chelsea's remaining away games) : United, City, Burnley, Southampton, Swansea and Newcastle.
They are in serious trouble IMHO. I think they are going to miss out on Top 4. Most people would have looked at Bournemouth and Watford and said that's their chance to consolidate 3rd, now however they are in a serious battle for 3rd to 5th and with by far the toughest away games and schedule of the three clubs.
