Not sure if he was serious: Marnus on Warner's 'available' remark

Reacting to David Warner stating that he's "available" for the Test series against India, Australia batter Marnus Labuschagne said, "I don't know if he was serious or whether he was joking." Labuschagne stated it is "hard to tell". "Just got to pick up the phone. I'm always dead serious," Warner had said. Notably, Warner retired from international cricket in July.
