Alistair Brownlee says brother Jonathan is 'tactical numpty'

Olympic champion Alistair Brownlee says brother Jonathan threw away the world triathlon title by being a "complete tactical numpty" during his battle with Spain's Javier Gomez at the Grand Final in London.

Alistair says the younger Brownlee got his tactics wrong by trying to outsprint the Spaniard from 200m out instead of sitting on his shoulder.

Gomez won his third ITU World Triathlon title as he beat Johnny in a dramatic sprint finish in Hyde Park.
