London 2012: Adam Gemili excited to face 'hero' Usain Bolt

Adam Gemili says it is "unbelievable" that he could face defending champion and his sporting hero Usain Bolt in the 100m final at the Olympics, but believes the Jamaican can be beaten.

The 18-year-old also says it is a "honour to represent Team GB" in the "blue ribbon" event at a home Olympics.

Gemili believes the men's relay team can reach the final and compete for a medal.
