Pakistan made less run in their innings and also they do not have the bowling line up to defend this small target.
Overall it was a bad series for Pakistan. They have lost both the ODI and T20 series and it will shatter their confidence before going into T20 World cup. They should have shown better performances specially in T20 matches.
There are a lot of positives that they can take from this tour. And for the T20 world cup, they definitely have an advantage, because the matches are going to take place in UAE and Oman, and the players are well suited to those conditions.
I feel Pakistan have no pressure going into the T20 World Cup because they’re not contenders for winning it, and hence they’ll be able to play their natural game and if they win matches then it’s added benefit for them. Furthermore the venue of the World Cup will support their team, hence I would not judge them based solely on this series.
