Paul Gustard defends England's decision to replace Rokoduguni with May

England defence coach Paul Gustard has come in support of Eddie Jones' decision to include Gloucester Rugby centre Jonny May in the place of Bath wing Semesa Rokoduguni for the upcoming clash against Argentina on Saturday.

Rokoduguni featured in his second Test after a gap of two years during last weekend's clash against Fiji and came up with a man of the match performance scoring two tries in England's 58-15 victory at Twickenham.

Despite, Jones' insisting that the 29-year-old's return should be handled carefully after he was handed a poor treatment following his debut against New Zealand, the 56-year-old decided to prefer May over Rokoduguni which certainly raised few questions on his tactics.

Rokoduguni's Bath team-mates Matt Banahan and Matt Garvey expressed their disappointment on the news of his axing.

Banahan tweeted: "Just caught up with the news Rocco has been released after his display at the weekend, what message does that send after a MOM #whybother?"

Garvey was equally confused by the axing of the 29-year-old, tweeting "Words fail me! #rokoduguni"

May, who scored a 10th minute try in the autumn series opener against South Africa will replace Rokoduguni while Elliott Daly will get another opportunity at left wing after his performances in the first two games.

Gustard said the team is selected based on the match-by-match basis keeping in mind the opponents on that day.

"We've seen this before haven't we between week one and week two of the autumn. Jonny May had a good game against South Africa and scored a try," Gustard said.

"On a game by game basis we have to pick a team that we think is most appropriate for the threats that we are going to face and for the opportunities that we want to exploit. He (Rokoduguni) along with several others miss out this weekend."

England are yet to lose a game this year and they are on a 12-match unbeaten streak. However, Gustard believes there is still a lot of scope for improvement especially in their defence.

"There have been some really good signs, positive signs and growth areas post the Australia tour," Gustard said.

"Unfortunately we've shipped a couple of unbelievably soft tries which is disappointing. We're better than that, but stats don't always reflect the performance of the team.

"We've spoken as a group of the need to raise our level again and that's what we're doing.

"We had a great day on Tuesday and we're looking forward to a good performance on Saturday.

"Yes we can be better, but we are the same group of players and same coaching group that conceded four tries in the Six Nations.

"We've not quite hit our straps yet. We know we can be better and we will be better on Saturday."
