Pakistan coach Bob Woolmer believes the team may have lost their nerve in their Champions Trophy semi-final defeat by West Indies.
Inzamam-ul-Haq leaves the field following Pakistan's defeat
"Most young teams that are growing choke occasionally," he said.
Skipper Inzamam-ul-Haq's decision to bat first did not pay off as they were all out for 131.
"Our original plan was the put West Indies in if we won the toss and chase, but the advice we had when we got there was contrary to that," said Woolmer.
"It took quite a lot of persuading for us to change but unfortunately it backfired on us.
"I am quite comfortable with the fact that if I made a mistake I am prepared to put my hands up and say so, but it wasn't done lightly."
Pakistan were favourites to reach the final after eliminating arch-rivals India in their previous game.
But the total against West Indies gave their bowlers little chance and they eventually went down by seven wickets.
Woolmer said, however, that he was generally pleased with the team's progress since he took over.
"The commitment, the desire to do well, is there.
"Batting has been a concern and one or two younger players haven't really fired yet, scoring 30s and 40s and not 70s and 80s, but I have identified why," he added.
Pakistan are set to host a triangular one-day series against Zimbabwe and Sri Lanka, which begins on 30 September.
At the end of the year they face a major challenge when they play three Tests in Australia, having been whitewashed on their previous visit in 1999-2000.
