WALES boss Warren Gatland has defended his 'passionate' fly-half Dan Biggar after England head coach Eddie Jones accused him of going over the top with his reaction to a controversial try.

England will head to Australia in fine fettle thanks to a 27-13 victory at Twickenham in which they scored three unanswered tries in the second half.

The middle of those came with the score at 15-13 when Biggar's pass on halfway was knocked down by tighthead Dan Cole with the ball scooped up by Harlequins back row forward Jack Clifford, who raced away and held off the challenge of Scott Williams.

Referee Marius Mitrea referred the decision to TMO Simon McDowell who declared: "Nothing clear or obvious, Marius you may award the try". It left Biggar, who had kept hold of the ball, fuming and the Ospreys fly-half remonstrated vociferously with the Italian whistler.

"I saw some games yesterday (the Aviva Premiership and Guinness Pro12 finals) where players were getting onto the referees when they made a decision and gesticulating," said Jones.

"When you look at the replays it's definitely a try. The ball went backwards," he continued.

"I didn't like how Biggar went on after that and I saw that yesterday. We've got to be really careful in the game that we don't allow that to creep in.

"The referee is a young referee and in these Tests coming up we are going to get young referees because they have to bring them through. We have to look after those young guys."

Gatland felt it should have been given as a knock-on – "it's a pretty important decision at a pretty vital time of the game for us to concede that try" – and defended the actions of his playmaker.

He said: "Dan was adamant there was a knock-on and that was just passion. There wasn't any abuse from Dan towards the referee – that would be unacceptable.

"There is nothing wrong with a player demonstrating what he feels is a pretty important decision and shows a bit of passion.

"Dan does get quite emotional in the game and has been working on that aspect but I don't have an issue with players showing some emotion like that because he just felt clearly the decision was wrong.

"There's always a reasonable amount of talking and 'refereeing' by players during the game."
