as the say in Days of Thunder 'he didn't slam into you, he didn't bump you, he didn't nudge you. He rubbed you. And rubbin', son, is racin'
Apportioning blame in a crash is difficult at the best times, claiming it was intentional ridiculous. The race is only a few stages old, plenty of opportunities to make time back, if he wasn't leader there wouldn't be any question of stopping. Plenty of riders have missed out on the chance of victory in a one-day race because of a crash, Valverde can get his revenge over the next few weeks at least.
Anyway he shouldn't blame Sky. Karma caused that crash
