Usman Khawaja believes one-day international cricket is "dying a slow death" and claims it is "very tough" to play in all three formats.

England Test captain Ben Stokes retired from ODIs this week, stating it was "unsustainable" for him to play for his country in the longest format, plus Twenty20s and the 50-over game.

Stokes warned that players cannot be treated like "cars" and keep clocking up mileage with such a hectic schedule.

Australia batter Khawaja is not convinced there is a long-term future for ODI cricket.

He said: "My own personal opinion – I know a few of the guys are very similar – you've got Test cricket, which is the pinnacle, you've got T20 cricket, which obviously has leagues around the world, great entertainment, everyone loves it, and then there's one-day cricket.

"I feel like that's probably the third-ranked out of all of them. I think personally one-day cricket is dying a slow death... there's still the World Cup, which I think is really fun and it's enjoyable to watch, but other than that, even myself personally, I'm probably not into one-day cricket as much either."

Khawaja believes it is a big ask for players to play in all formats.

"Not impossible, very tough," Khawaja said, quoted by the Australian Associated Press. "So much travelling. If you're playing all three forms of the game, you're not at home at all really.

"And then the demands on your body, mentally, physically and a lot of the guys might be playing also the IPL.

"There's a lot of cricket going on. Yes, you get to pick and choose, I guess, in certain respects what you want to play, but it can be very tough at the moment."

While Khawaja does not see a bright ODI future, he is not concerned about Test cricket.

"The majority of people I talk to still love Test cricket," he said. "It's my favourite format. [I] think Test cricket still has a very strong presence so don't really see that going anywhere."
