In reply to Fredt:
The BBC have reported the announcement that Froome is leading team sky as if it's a surprise

Very strong team on paper, but both Landa and Thomas have had their problems this year so might not be a good as expected. Then again with climbers like Henao and Nieve and machines like Kryienka and Stannard (and a monument winner like Poels, and a spare welshman in case the first breaks down), it is a very, very strong team.
Astana will be interesting to watch - will Nibbles really support Aru ? And stick with him if he has a bad day ? Likewise BMC. Reckon it could be a good year for the French, with Bardet and Barguil up there.
But Froome, Quintana, Contador is my prediction
As for Quintana having no skeletons in the closet - well his birth certificate must be a forgery for a start, he's more like 46 than 26
