Jonny Wilkinson is one of the greats - Sir Clive Woodward

Sir Clive Woodward says Jonny Wilkinson, who has announced he is retiring from international rugby, is "right up there" with other English sporting greats.

Woodward was England coach when Wilkinson kicked the winning drop-goal in the 2003 World Cup final, and says the fly-half "took rugby union to whole new level."
