Take RUSSIA +6 and thank me later 
If Greece wins they will propably face Spain (they have bad rekord vs them)
If Greece looses they face propably France.
What would you choose?
I would go for France 100%
Greece players state that they will play for win as always, but believe me they dont wanna play Spain, they are afraid of them.
Even straight win for Russia is value here.
Take Russia +6 and thank me later.
My 2 cents
