Iain Balshaw and Jason Robinson may well contest the full-back position
in the Test series against New Zealand, though both could face
competition from Wales' Gareth Thomas and Ireland's Geordan Murphy.
And Barkley believes the different skills of his England team-mates offer
coach Sir Clive Woodward plenty of options.
"Jason is much more of a freak," Bath star Barkley said.
"Jason is able to do things other players simply can't do. He is an out-
and-out attacker, but Balsh is an out-and-out full-back.
"Jason is a 30-metre man, whereas Balsh can sustain his pace and
maintain his line for 10 yards longer."
Barkley added of the Leeds captain: "He is very vocal from the back - he
offers good suggestions and ideas."
