They’ve been playing against our reserves and there’s been a real cutting edge in training.

We all know it’s on e last tournament and we’ll give it everything and then have our rest over Christmas. The group we’re in will take any chance of complacency away. Samoa, Argentina and the USA are all sides who have beaten us in the past three years.“Everybody will want to have a crack at us now but we think we’re on an upward curve. We need to be consistent and that means performing well at lots of tournaments.”This is the first time three tournaments have been played back-to-back in the World Series and when England return home on December 12 they will have travelled more than 33,000 miles on 10 separate flights across a dozen time zones in less than four weeks.
