With a strong batting lineup England has even though all of their players are in the team they will win easily, Pakistan surprised with one match and that is more than enough to expect from them and in this match England only need 61 runs to win in 54 balls with 8 wickets in hand and if Pakistan had a potent bowling lineup they once had then i might have given a chance but not anymore.
Although they managed to win only one match, none of their defeats were one sided. And that gives them hope. Pakistan has performed at a level much better than teams like Sri Lanka and South Africa (which recently lost an ODI match to Ireland). Outside the big 3 + NZ grouping, Pakistan seems to be the strongest team. And in UAE/Oman they usually have home advantage, because when Pakistan was unable to host matches, UAE used to be its home venue. But do they have a chance to win the world cup this time? It's a difficult question.
