Froomedog is going no where. Sky have as good as promised him next year's tour. I reckon rabobank will come in for cav. His old mate renshaw has bombed this year. He doesn't have the speed need to finish off. Rabobank need to up their win rate as its pretty shoddy.
The only other option would be if specialized pressure one of their teams to do it.
The biggest question is where will JTL be next season. He won't be at a continental team that's for sure!
