Australia, England and India are all in with a chance of ending January at the top of the ICC One-Day International team rankings.
India currently retain a lead at the top despite a 2-0 series defeat in South Africa in late 2013 and they can only be overtaken if they lose their five-match series to New Zealand.
Australia and England clash in the first match of a five-game series on Sunday 12th January in Melbourne while India meet New Zealand in the first ODI on 19th January in Napier.
Australia last topped the rankings in July 2012, when they were overtaken by England, who were subsequently replaced by India in December 2012.
With Australia trailing India by six points, they would need to beat England 5-0 and hope New Zealand win 3-2, or win 3-2 and hope New Zealand win 5-0, to go back to the top of the rankings.
They would also reach the number one spot if both series ended 4-1 in Australia and New Zealand's favour.
England need New Zealand to win 4-1 (in which case they need to beat Australia 5-0) or 5-0 (in which case they need to win 4-1) if they are to overhaul the current gap of nine points.
Should New Zealand pull off an emphatic win over India, they would leapfrog the West Indies into seventh place in the standings.
Neither New Zealand or the West Indies gained any places following their 2-2 series draw, although New Zealand gained one ranking point.
