‘I’m coming for you, Sarah’: controversial Kristina Vogel issues warning to Hong Kong medal hope Lee Wai-sze

Kristina Vogel has vowed to go hard at Hong Kong medal hope Sarah Lee Wai-sze on Tuesday but their Rio Olympics sprint quarter-final may be overshadowed by the German’s controversial comments calling into question "cannon fodder" Great Britain’s domination of the sport.

World keirin champion Vogel completed a "painless" 1/8 round victory over New Zealand's Natasha Hansen and warned that she will be fresh and hungry against the Hong Kong rider.

However, Vogel deflected attention from her best-of-three quarter-final by raising doubts about Great Britain, who have been in golden form in cycling so far.

“They were cannon fodder when you look at the last few years,” Vogel said of the British team. “Now they come along with a high level.

“I don't want to accuse anyone of anything but it is all very questionable.”
