After suffering a narrow four-run defeat in the first Test against New Zealand, Mickey Arthur has termed it as the "worst of his coaching career".
Pakistan were asked to chase a modest 176-run target, but they were undone by a shambolic batting display as they lost their last seven wickets for just 41 runs.
Left-arm spinner Ajaz Patel had a perfect start to his Test career as he picked up 5-59 in the second innings.
Arthur said Pakistan were hurting from the defeat, however his side will use it as a motivation to come back hard in the second Test.
"This is probably one of the worst defeats I have ever suffered in my career," Arthur, who also coached South Africa and Australia, told AFP.
"Everyone from myself as head coach to the players and the staff are hurting but we will use this defeat as a motivation to give ourself every opportunity to win the second game," said Arthur.
Arthur said his batsmen's shot selection was poor, having needed 139 on day four with all ten wickets intact.
New Zealand grabbed three quick wickets early on Day 4 before Azhar Ali (65) and Asad Shafiq (45) struck an 82-run partnership.
Arthur refused to accept his batsmen were complacent.
"There was no complacency, I can certainly say," said Arthur.
"The guys tried unbelievably hard and everyone was disappointed from the decision of shot selection under pressure. We need to learn from this and move forward very, very quickly."
Pakistan fell short while chasing 136 against Sri Lanka at the same venue last year and Arthur lamented his side’s failure to chase down small targets.
"The most disappointing thing was that it happened against Sri Lanka last year as well. That's the thing the batting unit needs to get over and that we need to chase down targets in fourth innings.”
Arthur also defended batting coach Grant Flower by saying the Zimbabwean works extremely hard with his batsmen.
"Grant works incredibly hard with the batsmen and his level of commitment and the work and efforts he put in is second to none."
