Curtis Davies will join Aston Villa on a season-long loan before signing long-term next summer ...
it is Albion who insisted the transfer is structured in this way .... there is no get-out clause for either club and Davies is certain to become Villa's player next summer.

I bet this gets them out of the 12.5% sell on clause with Luton
