That is the advice the world's top coaching guru, Frank Dick, offered to UK Athletics (UKA) yesterday.

Dick is concerned UKA will break not only their own regulations, but those of the International Association of Athletics Federations (IAAF) and World Anti-Doping Agency (WADA), if they bar the sprinter from the team.

Dick feels using UKA's "exceptional circumstances" selection rule will be a legal breach of their own and other constitutions, if used against Chambers.

He urged UKA performance director Dave Collins and his fellow selectors to ignore the moral crusade of chief executive Niels de Vos and pick Chambers in the first wave of selections being announced today.

De Vos initially tried excluding Chambers from the weekend's trials in Sheffield on the grounds he had not undergone sufficient drug testing since announcing his return to athletics after an aborted American football career.

But de Vos had to back down when overruled by the IAAF, who insisted the 29-year-old sprinter had broken neither their anti-doping nor competition rules.

Chambers's 60m victory at the trials should have guaranteed him, like other victors, selection in the Norwich Union GB side for the championships, which begin on March 7.

"I agree with de Vos' stance wholeheartedly, he's fetching a breath of fresh air to the sport," said Dick. "But if Chambers is left out, we'll be playing ducks and drakes with the rules.

"What we're seeing here is a dog-in-the-manger attitude and opening up a can of worms by making the rules up as we go along."
