Three-time Olympic gold medalist Usain Bolt has claimed that he is looking forward to taking on British sprinter Dwain Chambers at London 2012, despite the runner's previous history of drug taking.

The 34-year-old was not permitted to take part in this summer's Games due to a lifetime ban after being found guilty of taking drugs. However, last month the British Olympic Association had their bylaw overturned by the Court of Arbitration for Sport following a challenge by the World Anti-Doping Agency.

Now, the 100m sprinter will feature in the London Olympics alongside Jamaican world-record holder Bolt.

"For me, if the rules say it's okay for him to come back, then who am I to really complain," The Telegraph quotes Bolt as saying. "Is he a threat? As long as he is in a lane beside me, he is. I'm focused on whoever lines up beside me."

Bolt has already clocked the fastest time of the year with 9.82 seconds in a 100m race in Jamaica three weeks ago.
