England v Argentina: prop David Wilson is looking forward to facing 'gruesome' Pumas pack Asked what it was like to face the Argentina scrum, Wilson added: "It is a full 10 seconds, similar to a one-rep max [lifting your heaviest weight possible]. It sometimes hurts if you get it a little bit wrong, but if you get it right and you have got the weight behind you, it is a massively satisfying feeling. But it is a hard, gruesome thing. The new [scrum] laws benefit sides like Argentina, who have bigger stronger men and scrummage for a longer time. If you have a smaller, weaker pack who are always going to be playing catch-up. Wilson, whose 29 caps have yielded only 738 minutes on the field for England - an average of 25 minutes per game - is determined to seize his opportunity on Saturday to prove that he is a genuine alternative to Cole, who has started 39 of the last 41 Tests. Wilson's elevation has been down to his excellent form for Bath this season and the fact that he impressed Stuart Lancaster, the England coach, during the tour of Argentina in June, when he started both Tests. Wilson has worked hard on his mobility and fitness, which has helped him to broaden his game by making him more effective in defence and with ball in hand. "It has been a little bit frustrating," Wilson admitted. I thought scrummage-wise I could have come on and done a job at times when I have been sat on the bench and not got on. You feel disappointed in that but in the same breath you have got to give the coaches the confidence that you can come on and do the job in every other area of the pitch - tackle-wise, defence and attack. I obviously do want to start and even if I am on the bench I want to be used more, not just put on for five minutes but a reasonable amount of time so I can make an impact. It is tough for a prop. You get up from a scrum and you are blowing a bit and then someone gives up. You want the ball when you are fresh and there is not a lot of times in the match when you are fresh to be honest.
