QBE Internationals: weakened Argentina forced to blood new talent against England at Twickenham However, hopes could have been much higher for this tour, which also features fixtures against Wales and Italy, had Phelan not departed suddenly, Felipe Contepomi not retired, captain Juan Martín Fernández Lobbe not fractured an elbow and fullback Juan Martín Hernández not sustained a thigh injury while training with Racing Métro. So Daniel Hourcade, who coached the country's development side, the Jaguars, to a fourth consecutive Americas Rugby Championship title recently, replaces Phelan as coach, and for Saturday it is not only Hernández who is now unavailable to him from his original 31-man squad. Bath's Eusebio Guinazu, Worcester's Leonardo Senatore and Glasgow's Gabriel Ascarate are also missing because of club demands, to add to the disappointment of the unavailability through serious injury for the whole tour of Leicester wing Gonzalo Camacho and Montpellier forward Juan Figallo. Experimentation would seem to be in order, as that great former scrum-half, Agustin Pichot, now an Argentine union board member, points out. "In the Rugby Championship you can't improvise, but with this squad on this tour it's an excellent moment to try out players," he said. Argentina do seem keen to broaden their playing horizons, after scoring just seven tries in their six Rugby Championship matches this season. "What made an impression on me was something Graham Henry said, that Argentina must score more tries," Pichot said. The former New Zealand World Cup-winning coach Henry has now left the Pumas, having acted as a technical adviser during the Rugby Championship. "I didn't feel right," Henry said. It's either I do it 100 per cent or I don't do it at all. Doing it 70 per cent is not the right thing to do. I'd never done that before. It didn't work for me."" Whether a wider game will work for Argentina, whose traditional strength has always been the scrummage, is another question. They have appeared confused at times recently, uncertain in pattern and style. That said, they do at least possess a gem of a young player in flanker Pablo Matera, whom Leicester have had the great fortune of snapping up from under the noses of more wealthy suitors. The presence of prop Marcos Ayerza at Leicester apparently helped. The 20-year-old Matera can carry, offload and is a nuisance at the breakdown, prompting his club director of rugby, Richard Cockerill, to call him "one of the best young forwards in world rugby." Saracens are equally happy with their recent acquisition of centre Marcelo Bosch from Biarritz. The 29-year-old is obviously more experienced but he is a quality performer, too. Argentina do have some quality, but too little of it will be on show at Twickenham. Last summer they lost two Tests to England heavily, with both sides weakened. The teams will be very different next Saturday, but the result will not.
