In his new book, Michael Rasmussen supports Tyler Hamilton's claims that the American was introduced to doctor Eufemiano Fuentes by Saxo-Tinkoff owner Bjarne Riis. The former Tour de France king of the mountains details how they both took doping during the 2002 Giro d'Italia in the presence of Riis.

Last year Tyler Hamilton accused Saxo-Tinkoff owner Bjarne Riis of having introduced him to doping doctor Eufemiano Fuentes - the man in centre of the Operacon Puerto doping investigation - while riding for Riis's team then known as CSC-Tiscali. The accusations were made in his book "The secret race" but Riis refused the claims at the time.

Since then former CSC-Tiscali rider Michael Rasmussen has made a detailed admission of his own doping use which has prompted the Danish anti-doping authorities to open an investigation into the possible malpractices on the Danish team. Until now, Rasmussen hasn't detailed his accusations publicly but that will change on Monday when his book "Yellow fever" will be published in Denmark.

Danish media have had the chance to read excerpts from the book and pieces of Rasmussen's accusations are now starting to surface. In addition to his claims of systematic doping on CSC-Tiscali, he supports Hamilton's earlier claims.

"After Semana Catalana, I injected EPO three times to prepare for the Tour of the Basque Country. I was set to ride in support of Tyler Hamilton. I was well-prepared but he rode like an old lady," Rasmussen writes.

"Today I understand why he was so poor in that race. Riis introduced Tyler to the Spanish doping doctor Eufemiano Fuentes but I didn't know at the time. I wasn't ranked high enough in the hierarchy to be associated with him. It was probably Riis' way of risk management - only the star riders on the team were introduced to this world. Fuentes had collected his blood shortly before the Tour of the Basque Country. He was naturally weakened."

In 2002, Rasmussen was riding in support of Hamilton at the 2002 Giro d'Italia where the American finished 2nd behind Paolo Savoldelli. In the book, he describes how Hamilton doped during the race.

"He stayed in the top 10 during the Giro until he won the 30km time trial in Numana. I have since been informed that he was in Monaco to receive a bag of blood prior to that stage."

He details how Riis was present when they both received cortisone injections.

"I entered [team doctor] Piet De Moor's hotel room where Bjarne Riis and Tyler were both present. Tyler had just received a synachten injection and asked me to join him. I accepted. Bjarne had no objections. After all, the next stage was a 225km mountain stage. The doctors injection 0,2 milliliters in my shoulder.

"Afterwards, Tyler was reborn. He would have won the Giro on that stage if he hadn't had a hunger knock at the end. That's why he was only 2nd.

"Regarding myself, I had probably taken too much synachten. I was blocked as you say. If you take too much cortisone, the body may contain too much fluid. You may be blown up to an extent where you eyes almost get closed. The doctors on Rabobank described it as being "like the Chinese". I finished around 20th on the stage."

Riis refuses to comment on the accusation as long as the anti-doping investigation is ongoing. De Moor states that he has always worked in accordance with the rules.
