Sachin Tendulkar has labelled Glenn Maxwell's innings against Afghanistan the best he's seen in one-day international cricket, headlining a long list of praise for Australia's explosive allrounder.

Maxwell's unbeaten 201 from 128 balls has been widely endorsed as one of the greatest white-ball knocks of all time and helped Australia wrap up a World Cup semi-final spot.

After watching his side slump to 7-91 from the non-striker's end, a clearly cramped-up Maxwell took charge in a 202-run eighth-wicket partnership with Pat Cummins.

Maxwell's innings included 21 fours and 10 sixes, often dispatching the ball despite limited movement in his legs.

"From Max pressure to Max performance! This has been the best ODI knock I've seen in my life," Tendulkar tweeted.

The Indian batting legend was far from alone in his praise.

"I've watched and played a lot of cricket, and I have seen nothing like that," former Australia skipper Ricky Ponting said in commentary.

"Unbelievable scenes.

"He was done, down and out. He couldn't move. His whole body had cramped up.

"He stayed out there because he knew he had to get his team across the line, and he's done it. Unbelievable effort."

Adam Gilchrist, long regarded as one of Australia's greatest white-ball batsmen, agreed.

"Clearly the best ODI innings ever," Gilchrist tweeted.

"Has always been the most exciting player in the world to watch in my opinion."

Former international stars Michael Vaughan, Virender Sehwag and Wasim Akram were among others to class Maxwell's Mumbai miracle among the greatest of all time.

Former India allrounder and coach Ravi Shastri compared Maxwell's knock to that of Kapil Dev against Zimbabwe in the 1983 World Cup.

Dev's match-saving 175 helped India recover from 5-17 to 8-266.

Cummins, who had arguably the best view of the innings from the non-striker's end, was definitive in his praise.

"It's the best I've ever seen, probably the greatest ODI innings ever," he said.

"We're just chatting about it, all the players, and we've decided it's one of those days where you just go, 'I was there in the stadium the day Glenn Maxwell chased down that total by himself'."
