Australian all-rounder Glenn Maxwell may be rested from the first one-day international against Pakistan as the tourists recover from a stomach bug that has hit the team in the United Arab Emirates.
Maxwell missed training on Wednesday, two days ahead of Friday`s opener in Sharjah.
Spinner Nathan Lyon also missed training on Tuesday with illness but joined his teammates in their Wednesday session and has a good chance to be picked in a dual spinning assault with wrist spinner Adam Zampa.
"The stats from here, all suggest that spin takes a bigger impact," captain Aaron Finch said in comments published by Cricket Australia`s website (cricket.com.au).
"We even saw yesterday that the training wickets looked how we expect the middle to play. You`re never quite sure though, once there`s a bit of traffic on it they start to slow up pretty quick and spin a bit."
"I think that will be a feature, especially the two games in Sharjah."
Paceman Nathan Coulter-Nile re-joined the squad for the five-match series against Pakistan after missing the final three ODIs against India to fly home to Perth for the birth of his second child.
After trailing India 2-0, Australia won the next three games in succession against Virat Kohli`s side to claim their first series victory in the format in over two years and enjoy a timely confidence boost ahead of the World Cup.
Coulter-Nile, who is in the frame for the global showpiece event while seamers Josh Hazlewood and Mitchell Starc struggle with injuries, said there was a good mood around the camp despite fierce competition for spots in the World Cup squad.
"Everyone`s performing, that`s why we`re winning but even when someone has a bad day, they`re really supportive of other blokes who have had a good day," he said.
"It`s fantastic to see. I don`t think it`s a conscious effort that anyone makes, just think it`s good mates supporting each other."
"I don`t think anybody goes out there thinking, `I`m not going to worry about selection`. It`s just the way everyone is, they`re all just good people."
