Pakistan coach Mohammad Hafeez says his side outplayed Australia in the Boxing Day Test, claiming poor umpiring and the use of technology denied the tourists victory.

Hafeez questioned the consistency of decision-making from match officials in Australia's 79-run win at the MCG on Friday.

The result gave Australia an unassailable 2-0 lead in the Benaud-Qadir Trophy series.

"Our Pakistan team played better than the other team in general," Hafeez said.

"Our batting intent was better, our bowling was hitting in the right areas.

"Yes, we made some mistakes … but as a team I believe that there were a lot of positives within the team.

"I believe inconsistent umpiring … has really given us the result, which should have been different."

Hafeez was particularly upset about Pat Cummins's dismissal of Mohammad Rizwan (35), which left Pakistan on 6-219 in its chase of 317 for victory.

Rizwan was initially given not out, before the third umpire ruled the ball took the wristband on his glove through to wicketkeeper Alex Carey.

The Pakistan batter immediately remonstrated, pointing to a mark on his forearm where he believed he had been struck by the ball.

It proved to be a turning point on day four, with Pakistan losing 5-18 in 6.4 overs to be all out for 237 in its second innings.

"He [Rizwan] is a very honest person and he said to me he did not even feel that it touched anywhere near the gloves," Hafeez said.

"There should be conclusive evidence to reverse the decision of an umpire … and there was no very conclusive kind of evidence.

"Technology is basically putting the curse on this beautiful game of cricket."

'Technology is inconsistent'

Hafeez called for the removal of umpire's call on ball-tracking LBW decisions.

"We play this game for the fans, and the fans will never understand why this technology is inconsistent," Hafeez said.

"The ball hitting the stump is always out. Why it's umpires call, I never understand that."

Australia captain Cummins was blunt in his response to Hafeez's claim that Pakistan was the better team.

"They played well, but glad we got the win," Cummins said.

"It doesn't really matter, does it? It's the team that wins in the end."

Cummins also defended the umpiring in the match and use of technology across the sport.

"Some [umpiring decisions] go your way, some don't. There was a few umpire's calls for both teams," he said.

"I think it all evens itself out. I thought this game was pretty 50-50, so there's nothing that worried us too much."
