"The sample I provided in Indianapolis on 23 July 2003 was found to contain the metabolites of nandrolone in a concentration not exceeding 5ng/ml. However, this does not tell the whole story.
"What the sample analysis also indicated was the presence of the same common analytical fingerprint as that detected in over 46 other samples provided by professional tennis players on the ATP Main Tour."
Rusedski called on the ATP to investigate the whole affair and find the source of the trouble. An ATP spokesman denied any knowledge of 47 examples of elevated levels of nandrolone in players belonging to the tour.
He said "We are not aware of that. We don't know about four let alone 40 or 400. When we announced that there were seven players last year who had been tested positive after receiving supplements from official trainers we made it very clear how the substance came to be found."
