Steve Diamond: Key principles driving Sale Sharks revival

Director of rugby Steve Diamond tells BBC North West Tonight that a number of "key principles" have been important to Sale's revival in the opening weeks of the season.

The Sharks - who lost their first seven Premiership matches in 2012-13 - have made a much brighter start to this campaign, winning three of their first six games.

Sale host Exeter Chiefs on Friday.
