IF Alberto went to the Alonso team, he'd need some help for the TTTs. Can't be bleeding time to rivals every TTT like poor Sammy has had to do for years. Hiring LL Sanchez would be a nice start in that department...
Recently there were reports about Bjarne going to CAS to get them to rule that Contador's points should count towards a WT license. Which wouldn't really be needed by Saxo. They might be more useful at an Alonso team, though. But why in hell would Riis be launching a CAS case to help another team???
As for Specialized, they already sponsor 3 teams with several big stars that they do independent marketing with - Cav, Nibali, even Boonen. It could be that Spesh is willing to let AC go, seeing his stock as falling, and focus more on Cav and Nibs (whose star is still rising).
As for Tinkov, earlier this year it seemed that Kreuziger was his pet on the Saxo team. However, he changes on a dime, so who knows?
IF Alberto came to the Alonso team, I could see somebody like Flex or Anfi picking up some sort of sponsorship alongside Banco Santander.
