England wary of New Zealand winger Julian Savea

Savea will be hoping his try-scoring run against England continues on Saturday as his team go in search of a series whitewash.

The 23-year-old has scored five tries in three games against Stuart Lancaster's side " a quarter of his 20 tries from 21 Test matches.

Savea's most recent was last weekend's effort in the 28-27 win in Dunedin, which gave the All Blacks an unassailable 2-0 series lead.

The 193-centimetre winger's blistering pace, good step and size make him a difficult man to stop as the English have found out.

In his first Test at Twickenham in 2012 he scored twice in a losing effort and he repeated the feat last year at the same venue when New Zealand exacted their revenge with a 30-22 win.

The only other team Savea has been as prolific against is Argentina where he has five tries from four Tests against the Pumas.

Savea's five-pointer last weekend came in a dazzling 20-minute spell, which also saw Ben Smith and Ma'a Nonu cross the white line to take the game away from the English.

Savea missed the first Test of the series in Auckland with a knee injury and faced Manu Tuilagi on the wing last weekend.

Lancaster has shelved that experiment for now and sent Tuilagi back to his regular midfield spot for Saturday's clash at Waikato Stadium, which has left Chris Ashton with the job of trying to corral Savea.

"He just offers a different threat on the wing," Ashton said.

"He's a big bloke and he can move and do everything that a modern rugby player can to the absolute best.

"Once they get going " as we saw in the 20 minutes in Dunedin " they are pretty lethal with it.

"Trying to keep him under wraps is pretty difficult with the other threats that they have. You've just got to do your best with him."

Ashton himself is no slouch when it comes to try-scoring either.

He only got a few minutes off the bench at Forsyth Barr Stadium but still managed to score.

It is that ability to put himself in the right place at the right time that Lancaster wants to see more of from Ashton, who lost his Test place for this year's Six Nations after a slump in form and confidence.

But Ashton's form for Saracens in the second half of the season has prompted the recall.

"I've just enjoyed it again. You sometimes lose that a little bit when you try too hard," Ashton said of his turnaround.

"Sometimes you forget that and that's the main reason why I'm here.

"Confidence is a funny thing sometimes. When things aren't going your way it is hard."
