Shane Geraghty is set to emulate his mentor Mike Catt and strike a devastating midfield partnership with Jonny Wilkinson in the showdown with Australia. The 23-year-old, who will make his first England start at inside centre, learned his trade alongside Catt at London Irish before making a successful summer move to Northampton. Wilkinson always revelled playing with Catt, who not only brought an alternative attacking threat to the England team but, crucially, also acted as his eyes and ears. Wilkinson said: "Communication is so important. I had that with Mike Catt. So many times when people have said I had a good game, I actually came off the field thinking I had done nothing." Geraghty, who has been one of the form players in the Guinness Premiership so far this season, believes he can play that Catt role and bring the best out of England's returning World Cup hero. Geraghty said: "It wouldn't be a bad model to emulate. That is probably the closest England have had to what we have got this Saturday. "Jonny and Catty always had a good balance and great blend. They worked off each other and I am looking towards that."
