Do you believe Chelsea's title defence is defined by Diego Costa's fitness?

Harry Redknapp believes that the fitness of Diego Costa this season is key to Chelsea's title defence and I just wondered how many of you believe that this IS the case?

Of course we have to consider Loic "Offside ten times" Remy and Radamel Falcao but for me Costa is key because he embodies everything we are about.

He is the closest striker we have to Drogba and has the same presence up top which our team has been set for ever since Jose Mourinho was first in charge.

Costa is a MAJOR concern for me ahead of the new season with his hamstrings flaring up again leaving him as a doubt for Swansea this Saturday. We MUST do everything we can to persuade him to either have an operation or something to try and put an end to the ongoing problems he has been faced with.

Harry Redknapp said the following:

"If Costa is injured a lot and is going to be missing, that's the scary part - can they (Chelsea) get away without him?

If Costa does pick up injuries, and it seems his hamstring isn't great at the moment, one of (Loic) Remy and (Radamel) Falcao has got to carry the baton and do the job and whether they can is the question mark.

Maybe Falcao can do the job, Jose's placed his faith in him. Jose (Mourhino) can lift people and improve people and if he can get the best out of him maybe they'll be ok."

What do you think on Costa, on Falcao and on Remy? Do you think if Costa is out for an enforced period of time, we have enough without him?
