while chelsea will rest some players and have a few definitely out, such as john terry, their team will still be stronger than most premiership sides.
and while they have wrapped up the title and a few records, they have more records they wish to set and extend, plus there's arsenal's record of most consecutive games unbeaten to aim for.
newcastle have their own selection problems - ameobi is suspended and kluivert is doubtful. it's been such a difficult season for the club that most are probably just looking forward to it being over.
so i would be tempted to back chelsea if i was going to have a bet.
