According to them it's also not 100% sure that Ineos will bring him to the Tour and not the Giro or the Vuelta.
If Ineos actually told Froome that, I'd think that for him that would be the last straw, and that he'd definitely want to switch teams now. He doesn't have many more shots at the TDF left, I'm sure he'd rather take his chances with three leaders than not ride at all.
