Team Sky chief David Brailsford has voiced his criticism of the chairman of UK Anti-Doping.
He has also stated that he will not consider his position as the boss of the Tour de France winning cycling outfit.
The team's general manager recently appeared in front of a UK Parliamentary committee, facing questions over a package delivered to Bradley Wiggins at the 2011 Dauphiné.
Brailsford informed the committee that the package in question contained a legal decongestant called Fluimucil.
It is a drug which is used to clear mucus and is not subject to any controls by the World Anti-Doping Agency.
UK Anti-Doping (UKAD) chairman David Kenworthy had commented on the parliamentary committee session in an interview with the BBC earlier in January.
"People could remember a package that was delivered to France, they can remember who asked for it, they can remember the route it took, who delivered it, the times it arrived. The select committee has got expense sheets and travel documents," he had said.
"So everybody can remember this from five years ago, but no-one can remember what was in the package. That strikes me as being extraordinary. It is very disappointing."
Brailsford maintains his and Team Sky's innocence, and says he feels secure in his position at the helm of the team.
But he was also critical of Kenworthy in an interview with Press Association Sport.
"The only extraordinary thing, I think, was the chairman of Ukad’s comments the other day when he commented about an ongoing investigation. As an organisation like Ukad and for the chair to say it is an extraordinary thing - that’s the extraordinary thing in itself," he said.
