Tyler Hamilton, a team-mate of Lance Armstrong, believes the disgraced cyclist will not stay silent for too much longer.
Hamilton was part of Armstrong's US Postal outfit from 1999 to 2001, a period in which Armstrong won three Tour de France titles, and was one of those who gave evidence as part of the United States Anti-Doping Agency's case against the Texan.
The 41-year-old has been one of Armstrong's most vocal critics but as of yet Armstrong has said little about the decision to ban him for life and strip him of his seven Tour titles. However, Hamilton expects this to soon change.
"You hear very little from Lance, but I think this will not be a permanent state. I fear Lance will hit back," Hamilton told German magazine Stern.
"I think he is suffering a lot. He is a very proud person and thinks that - like Atlas - he can carry the whole world on his shoulders. Now everything is gone, the honour and the glory. I think it will tear him apart that he is no longer a hero."
