Usain Bolt wants 'four years of dominance' - Diamond League

Triple Olympic champion Usain Bolt aims to "dominate for four years" before retiring from athletics after the 2016 Rio Olympics.

The 26-year-old Jamaican says he's "feeling great" and "everything's coming together" ahead of his return to Europe in Thurday's Diamond League meet in Rome.

Bolt became the first athlete to retain the 100m and 200m at the 2012 London Olympics and holds the world record in both events.
