I hope so, and I think so, and I know he must be thinking that. I thought that last years as well, becouse he was stronger than Aru on Trentino and Nibali said that Landa would be very dangerous in the Giro, but Landa crashed, and lost time, he had a similar Giro that Porte this year, and he was just working for Aru, taking bottles of the car and things like that, helping some days in the mountains.
I think that with the help of Aru, 4 minutes is not too much with a difficult stage, the Queen stage of this Giro, Cervinia, and another, long as well, with Finestre.
But Contador is strong, he has an strong team, he hasexperience and if he is clever he can lose time but never the Giro.
But I know Alberto quite well, he dont want anybody said Landa was stronger at the end of the Giro, maybe Landa climb always better than him all the Giro, and he wanst unleashed, Alberto is really competitive, he dont like never lose, so he will try that Landa dont take any time, or just a little that he can said, there were 2 againts 1, but he is not lo allow Landa put more than 1 minute on him any day, so that is the only thing that could make Alberto lose, his ambition... but Landa now, climbs stronger than Alberto, and with 2 stage like that at the end of the Giro, Landa is going to put time, I am sure 4 minutes? I dream with that, difficult, of course, but posssible, Savoldelli losed only in Finestre stage 2 minutes, and although Landa and Contador are climbing clearly slower than Pantani, Tonkov, Gotti, and those people, differences are going the same or more, becouse in Mortirolo stage, the 18th was at more than 10 minutes.
Of course is alberto has again some problem as punctures, crash,...easier...
Landa has had very bad luck along his career, the same as Urán, but This Giro everything is perfect for him, no crash, no bad luck, perfect shape, no pressure, just help, quite protected, work a little, strong team, hight motivation.. the only problem, and ITT too long, but a GT must be like that, and he did a decent ITT, and well, it would be better he were free before today, but it is normal how things has happend, Aru deserved that leadership so far..
