Literally nothing to play for?

Looking at the Premier League table would it be fair to say that after last night's defeat by Liverpool, Chelsea have nothing to play for on Sunday? They are four points behind Newcastle so they cannot catch them and are eight points ahead of Everton and so cannot be caught. With the Champions League final coming up could they put out a team of reserves so as to ensure no injuries or do they need a practice game for the team that will play in the final? Mind you Blackburn Rovers are not really comparable with Bayern Munich.
