Chisora bullish ahead of Klitschko bout

Dereck Chisora insists his fearlessness and "swagger" will prove decisive when he bids to pull off a shock against Vitali Klitschko this weekend.

Chisora, 28, takes on the Ukrainian WBC champion in Munich as the rank outsider on Saturday, attempting to dethrone a man who has reigned supreme for four years since coming out of retirement.
