Aru showed some legs, but since this was stage 5 it's really hard to predict if he's gonna have enough steel in his muscles to rip the yellow of Froomes back. Also other contenders might still pick it up (tho didn't look so)
Aru knows how to win GTs though, unlike for example Porte. BMC looked amateurish, chasing the break then getting swamped by the Sky train when it mattered, so Porte was isolated.
