Yes, I think he was mentally tired and of must when that happens, your body disconnects. Tiralongo got got right when he said AC was not mentally in tune for this TDF, the doping case and the feeling that the french did not want him. Yes he is mentally tough but the crashes, the knee, he said "forget this".
He definitely needs a stronger team. Saxobank has given BR virtually an open check to buy folks to support Alberto. They like him, I saw the video where he visited Saxobank's head office, they all had fun.
Not this year, for the double. I did say he should have skipped TDF. Speaking about Saxobank, notice how the team mates seem to abandon him on the road when something happens? I really question the loyalty to the leader. Perhaps, there are hidden issues? like in Astana?
I think Saxobank should do a new slate and get folks completely dedicated to the goal of AC much like LA did in all his teams. I think if he has that then the double becomes closer. And perhaps the triple, maybe the ultimate the Super grandslam (with the World championship)
