Yeap, the result was expected as because the ground is also on the England and as well England is much stronger in Batting and bowling than the West Indies team.
Moreover, if this had been a T20 match instead of an ODI match, then perhaps the West Indies team could have been put in a strong position there, although they are still behind England there. However, apart from the first match, the West Indies team tried their best in the last two matches but the ground favored the England team.
Yes , you are absolutely right. England International cricket team is top most cricket team of the World in ODI and test especially but West Indies have top class players in T20 format but there are many players who prefer league cricket as comparison to International cricket because their payment is very low in International format but when they became famous then they join league cricket. West Indies cricket is not growing due to that reason. England cricket team won the series by 3-0 and that was expected.West Indies cricket team will play first T20 International against England tomorrow and that match will be interesting because West Indies team is favorite for T20 cricket.
