Pat Cummins says popular interim head coach Andrew McDonald must take great credit for the "huge part" he played in Australia's 1-0 Test series win in Pakistan.

McDonald was placed in temporary charge following Justin Langer's shock resignation last month.

The 40-year-old oversaw Australia's first overseas Test series triumph in six years, Nathan Lyon taking 5-83 and Cummins 3-23 on the final day to secure a 115-run victory at Gaddafi Stadium.

McDonald is the favourite to land the role on a permanent basis and captain Cummins is full of praise for the former all-rounder.

Asked about the job McDonald has done, he said: "Fantastic. Not unexpected. He's a great operator.

"The boys absolutely love him. Very diligent, very thorough, strategic, very organised. He's a huge part of this tour win."

Cummins would clearly welcome a decision for McDonald to stay on.

The paceman added: "His preparation, and all the support staff's. It's not just the 11 players who walk out; we've got a squad of 30-odd people who have been working so hard this month, and it's also important.

"I've said before it's not my place to employ the coach, but Ronnie [McDonald] has been fantastic."
