Reason for the Failure of Pakistan team in One Day Series

Pakistan team has been touring the Srilanka for whole tour which include One day series,T20 and also test series.Pakistan has level the T20 series and lost through the One Day series.There lost in the ODI series is because of the fact that Pakistan has not planned correctly They have not send player according to the Field.And also the fielding of the Pakistan team also gone below standers and it seem that player has not been doing well in the game.They are not focused.Some thing may be back in their mind which is disturbing them and may be the Srilanka Team has been playing after making changes by making their Capitan down to the order work for them and all of the player has response well.
                 Pakistan Team has to think that which is the best combination for them and how to improve the batting line up for Pakistan and which player will come on which position and what are the main trike bowler for them which should be played in the line up.After doing this i think Pakistan Team has the potional to become the number one team in the world.
