England travel to the World Cup in South Africa in March as one of the favourites and the Notts trio will all have crucial roles to play.Bates said: "Jane has been a constant in the side since I took over as coach and her experience will be vital as the only full-time wicketkeeper in the squad."Nicky has just got back to fitness after a tough 12 months with an ankle injury but as our batting all-rounder will be a key member of the squad."And Jenny's profile has risen since she first broke into the international set-up, with some excellent form with the new ball this summer."Bates named Australia as favourites for the eight-team tournament and also included New Zealand and India as teams to watch out for.But he added: "We have won our last four series of internationals, including this summer's series with the holders New Zealand and confidence is certainly high in the squad."The self-belief is there and although there's a tough schedule of matches to fight through, we don't fear anyone."England arrive in South Africa on March 8 and will start their campaign on March 22 against Australia.
