England v France: Will Greenwood says Morgan Parra and Wesley Fofana are key to Six Nations 2013 showdown People are correct to fear them; a wounded France is a dangerous beast. But it is also true that their iron determination to avenge their recent losses will give England their best opportunity to emerge victorious. As France worry about the big picture, England can focus on the small details. So where can England eke out an advantage? First up they need to target the back three. I expect to see a lot of kicking to Benjamin Fall and Yoann Huget. I do not think they can handle the high ball and their defensive alignment is poor. This gives England an "in" because their kick chasing has been strong so far in the Six Nations. Kick chases are determined by line speed and shepherding the opposition into the channels you want them to use. It is very similar to the blitz defence in this sense, which is lucky because that is another tactic that England will need to use against the French. The visitors tend to get tight very quickly and this sets them up perfectly for the blitz. England have to commit, close down and suffocate the French. Get them on the back foot, get them flustered and France have a tendency to short-circuit. For this to work, England will need to go low in the tackle. This is not a game to try and stand the French up in a choke tackle. They are big men with a lot of experience. However this means they also have some years on the England team. Put them on the floor and make them work for every yard. Lancaster's England have youth on their side. Then turn a strength into a weakness. Other areas England will be looking to exploit: Mathieu Bastareaud. The big man is real danger when he gets the space he wants. The key to neutralising him is to give him the space that you want. Invite him into a gap, bet on the fact that he will not pass and isolate him. Turnover opportunities will arise if you do. Another man England must look to target is Louis Picamoles, the powerful No8. He was brilliantly destructive in November when he looked like the best in the world. But he has his weakness; he carries the ball only in his left hand. He is scarily one-sided in fact. Go after it. A large part of shutting France down comes from shutting Picamoles down. First man go low, you cannot go high on Picamoles, he is too big. Once the first man has hit, the second man needs to go after the left hand and stop him offloading. France are in such a state of mental weakness that if they lose this attacking threat, they will lose pretty much everything they have. They have, though, made some changes that have made me less confident of an England victory. A week ago, I had England winning by 18-20 points. Today, it is much tighter. The selections of Morgan Parra and Francois Trinh-Duc at half-back have strengthened a weak point in the spine of the team. Owen Farrell will find it much harder to rattle Trinh-Duc, who at 6ft 4in is not one to be bullied. Parra is exactly what France needed - a class operator who understands how to win at the highest level. And France's scrum will be a very different animal this time round. Against Wales at the Stade de France they were depowered by the terrible state of the pitch, which cut up horrifically. They could not get a platform as the pitch ploughed up. Twickenham is in fantastic nick and the selection of Thomas Domingo at loosehead prop means France will be looking for a repeat of the scrum penalties they managed to win against the Italians. But the real threat for England is away from the scrum and now lurks in the centres. Wesley Fofana, a man who Jonny Wilkinson calls "agile, balanced, deceptively strong," a man who I think is the best centre in the northern hemisphere, is finally back where he belongs. Why Saint-André was picking him on the wing was mystifying. In the opening two games of the Six Nations he was anonymous out there. Against Wales, if you ignore a hospital pass from the kick-off, he touched the ball for the first time in the 48th minute. It was a spectacular waste of talent. Fofana runs the best lines in the game, and can open any side up. England just need to make sure they are ready for him. Because if they are, then there are plenty of other small reasons why they can go on to win.
