Captain Azhar Ali shouldered the blame for Pakistan's disappointing 95-run defeat to England in the second one-day international on Friday.
Having won the opening contest of the four-match series by six wickets on Wednesday, Pakistan were looking to take a commanding lead in Abu Dhabi.
However, Alex Hales scored a maiden ODI hundred and put on century stands with Jason Roy and Joe Root to guide England to 283-5.
Pakistan then wilted with the bat and were 50-5 at one stage, before Sarfraz Ahmed's 64 helped the designated hosts recover to 188 all out.
Azhar, who made 22, admits the top order did not do enough with the bat.
"We didn't play the brand of cricket we wanted to play," he said.
"We didn't start well, lost wickets and we had no momentum in the innings. I take responsibility for that, it [the poor start to the innings] put pressure on players to come."
England looked likely to post a score of over 300 but Pakistan's bowling attack limited Eoin Morgan's men, and Azhar credited his attack.
"We were expecting that England would come hard," he added. "We had a good performance in first game. Today the bowlers did really well, contained them to 283 when at one stage they looked like making 300 plus.
"The bowlers worked hard and restricted England to a total that we should have chased."
