Rashid’s leg-spin has been at the forefront of England’s rise from also rans at the 2015 World Cup to No 1 in the rankings and favourites to land the trophy for the first time next summer.
In the three-and-a-half years since their meek exit from the last tournament the Yorkshireman sits second only to Afghanistan prodigy Rashid Khan in terms of wickets taken in one-day internationals.
The wrist-spin duo are head and shoulders ahead of the competition, with 118 and 115 dismissals respectively, while their nearest challenger, South Africa’s Kagiso Rabada, boasts 86 in the same period.
Rain has restricted Rashid to just 17 overs from a possible 40 in the current series against Sri Lanka, which England lead 3-0 going into tomorrow’s finale in Colombo, but he has again proven his value with five wickets at 17.40.
“He’s always had skill and ability and potential, but I think now he’s at his peak as a spinner,” said Moeen.
“He’s got all the skills, he can actually bowl like Rashid Khan, he can bowl like any spinner. He’s got all the balls and I think now he’s really found his pace and his trajectory he’s a fantastic spinner and he’s right up there.
“I know Rashid Khan is probably the best, but I think Rash, in my opinion, is even better.”
Whether Rashid shares his friend’s conviction is, perhaps, another matter.
The 30-year-old has been accused of being fragile at times in his career, leading to question marks over his self-belief and ability to cope with pressure.
The softly-spoken Moeen hardly qualifies as a brash self-promoter either, but he agrees a drop of bravado could be useful for Rashid.
“Rash could be a bit more confident, that’s the only thing I would say,” he added.
“He’s got all the ability and skill so I do feel he can be a bit more confident. Sometimes that’s not in his nature, whereas most leg-spinners are normally confident even when they’re bowling pies.
“He’s always level headed and he doesn’t take things for granted, but as a leg-spinner in particular you have to have a bit of confidence.”
Rashid’s brief, self-imposed exile from red-ball cricket may now be over, with a new deal at Yorkshire and a full ECB central contract in hand, but he has yet to find the same level of success in the Test arena.
The three-match series in Sri Lanka, on spin-friendly surfaces, could be a turning point and Test captain Joe Root could do worse than take his lead from limited-overs captain Eoin Morgan.
“He’s right up there with the best captains I’ve played under,” said Moeen.
“The biggest thing as a spinner is when you go for a four his body language doesn’t go, he doesn’t make you think you’re not bowling well.
“That’s massive for a spinner. I know Rash says the same thing. If you feel like you’re struggling he never makes you feel like you are.
“It’s great for us that we have a captain like that and it’s one of the reasons we are No 1 in the world.”
Rashid’s Yorkshire team-mate Jonny Bairstow faces a race to be fit for the start of England’s Test series against Sri Lanka after being ruled out of the last two games of the limited-overs series with ankle ligament damage.
Bairstow missed the fourth one-day international after hurting his right ankle playing football on the eve of the match and was taken for a scan in Colombo yesterday.
He was subsequently told he would not be available for the final match of the series tomorrow or the stand alone Twenty20 that follows three days later.
Whether he will be ready to take part in the first Test, which begins in Galle on November 6, playing as either a specialist batsman or wicketkeeper, is not yet known.
An England and Wales Cricket Board statement said: “He will be monitored and assessed on a daily basis by the England medical team in Sri Lanka and a further update given in due course on his fitness ahead of the three-match Test series next month.”
Bairstow will need to be at the peak of his powers if he is to take the gloves in Sri Lanka, a demanding task that is likely to involve long passages of play standing up to the spinners in sapping heat.
Jos Buttler does the job in limited-overs cricket and deputised against India for one Test when Bairstow was suffering with a broken finger last summer. The Yorkshireman is reluctant to give up the role, though.
England captain Eoin Morgan has confirmed that football, the current squad’s much-loved warm-up of choice, will not be banned and several players took part in a game on the morning of the fourth ODI.
