Glenn Maxwell's unbeaten 201 in Australia's win over Afghanistan should be considered as the "greatest ever" ODI innings.
Earlier in November, Maxwell dragged Australia – who were chasing a target of 292 – to victory from 91-7 despite battling a back injury that was hugely limiting him.
On Sunday, it was fittingly Maxwell who struck the winning runs as Australia overcame hosts India by six wickets in the final.
And former England bowler Sidebottom thinks Maxwell's knock against Afghanistan will likely go down as the best in 50-over cricket.
"As an ODI innings, I've been lucky enough to watch and see many great ODI innings, but that has to be one of the best ever," Sidebottom told Stats Perform.
"It was just some serious hitting and display. I was in awe, it was seriously one of the best things I've ever seen.
"And again, I've got to say, Afghanistan were brilliant throughout this tournament.
"Afghanistan could have quite easily qualified [for the semi-finals]. It was a truly wonderful innings and to see how he played was just something very, very special."

Asked to consider other great innings, Sidebottom pointed to Ben Stokes' heroics for England in 2019, but thinks Maxwell's tally, which came off 128 balls and included 21 fours and 10 sixes, is the greatest.
"There's been so many from so many greats," he added.
"Stokes in the 2019 World Cup final because of the situation and England were struggling a little bit at the time.
"I look at how they go about the innings when their teams are under pressure. But Maxwell was under pressure to score 200 on his own to win that – it has to be probably the greatest innings ever."
