Fair play to Contador for showing this form after his injury, whatever you think of him too he's an exciting rider to watch. It was great to see Froome have a real go even if he's not quite 100%. Seems like he can probably go on and take second place behind Contador now and out time into Valverde on the last big climb and short TT.
Nibali was in unbelievable form in the tour and Quintana can blow things apart in the mountains but I think on form Froome and Contador are the bets GT riders out there. There was a quote from Contador in the last few days saying Froome was probably the strongest rider he's faced. The interesting thing about this duel is that when both are bang on form they're almost even in the mountains maybe Contador a tiny bit on the super steep stuff but Froome has the edge in the tour style TTs. Let's hope we get to see a proper battle in next years tour and that Nibali and Quintana are also there as it had the makings of one of the best.
