Instead of being a smart*** why don't you address the topic.
You can dress it up all you like, it doesn't matter if Froome is doped to the gills it still doesn't make it right to respond to his tweet in that manner. I see afterwards he said he did it because Froome has moved to the dark side. Therefore the response and topic belongs in the clinic. If you want to endorse cheap and low shots like this, you've lost all sense of reality.
Nothing wrong with Froome's tweet and Vayer just shoot first, think second. I hope he takes it back.
