Babar Azam was left to rue "soft dismissals" but says he has "full faith" in Pakistan after they suffered a 1-0 Test series defeat to Australia.

Nathan Lyon claimed 5-83 and the magnificent Pat Cummins took 3-23 as the tourists bowled Pakistan out for 235 on the final day to win by 115 runs at Gaddafi Stadium.

Imam-ul-Haq made 70 and the brilliant Babar 55, but Pakistan crumbled from 142-2 as Lyon snaffled a 19th five-wicket Test haul and man of the match Cummins finished with match figures of 8-79.

Captain Babar knows Pakistan only have themselves to blame after watching Australia get their hands on the Benaud-Qadir Trophy.

He said: "We didn't go defensive, we played positive cricket. You plan according to the situation. It's not like you go out, play big shots and go for the runs.

"We had a good session early in the day, but unfortunately we had soft dismissals and that's the reason we lost the game.

"We had a simple plan: to take the momentum in hand first and then think [about chasing the victory] after the tea. After lunch, we had a plan to play normal cricket.

"We weren't able to decide whether to go for a win or a draw. But with all those wickets falling, we decided to go deep as much as we could, but we were positive throughout.

"There were continuous discussions in our dressing room about chasing it down. But when your main batters are dismissed, you obviously start thinking differently.

"Still, Sajid [Khan] and I were trying to build a partnership and extend as much as we could, hoping we could draw. Yet we never held back, kept on playing shots and utilised whatever came in our area. So the mindset was positive but it didn't go in our way."

Babar is totally behind his players and is not contemplating making changes.

He added: "Overall the series went well, especially the Karachi Test where we dominated and saved the match. Unfortunately, I got out but even then we had our mindset on chasing.

"But mistakes are part of the game and it's too early to think about changes [to the team]. We don't have to forget their recent performances.

"Our entire team is experienced now, we have developed a good combination and I have full faith in them."
