It cannot be said that West Indies will change their perform. Because if there was a change they could gradually bring it to their team. But nothing like that can be seen in them. And the team is not strong enough to improve itself at once. Yes England are look themselves in good form and are trying to win the match and they have won the match. If it is against the West Indies it is difficult to say that the West Indies will win. Because West Indies cannot match their perform and win the match. According to my predict England will definitely win this match because Sri Lanka perform is good but not equal to England. Therefore it is difficult for Sri Lanka to win. West Indies need to perform well in themselves. If they lose to England if they keep their perform like that they can become a strong team.
