Froome frustrated as doping questions intensify

The yellow jersey holder let his frustrations show for the first time as the questioning intensified in the wake of his stunning display on top of one of the most feared climbs in world cycling.
Although Froome had dealt with the matter calmly during his first week in the maillot jaune, Team Sky’s patience is beginning to wear thin and team principal Dave Brailsford appealed for ideas as to what they could do to answer questions conclusively — suggesting he would open his doors to World Anti-Doping Agency (WADA) to come and give their verdict on whether Froome’s results are credible.
