Teams' current ODI form is going to play a crucial role in the world cup scheduled to be held in England & Wales in 2019. England and India occupy top two spots in the ICC ODI ranking. India is on tour of England, and after winning the T20I series, the visitors are set to play the 3-match-ODI series.
Currently, team India is just behind England with the rating of 122. The series of 3 ODI matches can help push India to the top only if they win whitewash over England by winning all 3 fixtures.
On the other hand, for England, winning any number of matches would increase the rating gap between the two teams. After the whitewash over Australia at home, confident England is sitting on top of the table with a ranking of 126.
If England wins all the three matches, then 4-ratings difference will jump to a whopping margin of 10 ratings in the ICC's ODI ranking table.
