In reply to Rog Wilko:
More likely he wants a final chapter to his book. If he'd won a couple of years ago on the Champs it would have been a beautiful send off, if he'd won one more stage this year, it would have been beautiful, as it is, his last chapter is him sitting in the road with a broken collar bone.
I am joking here. But, every great sportsman writes an autobiography right, and the current ending is a bit rubbish.
