Italy, meanwhile, had a tough initiation at the T20 World Cup with a 73-run defeat against Scotland. They also lost their captain Wayne Madsen to injury inside four overs of their T20 World Cup debut. He will not feature against Nepal either.

Italy coach John Davison said after the loss that the “occasion may have got big on us”. With nothing to lose and experience to gain, Italy have another chance to have fun and potentially upset some calculations, before facing stronger oppositions England and West Indies.

Batting at No. 5, Ben Maneti was one of the positives for Italy in their loss to Scotland. He started with only seven runs off seven balls, but went on to smash 52 in 31. The majority of his runs came against spinners (45 runs in 25 balls) with shots all around: behind square, through cover, and over the bowler’s head. Italy will hope Ben Manenti carries that confidence against Lamichhane and co.

Lokesh Bam threw everything he had at England when they needed 54 in 21 balls, but fell agonisingly short. Facing quality and experienced bowlers, he smacked back-to-back fours off Sam Curran and successive sixes off Jofra Archer as England searched for answers. Bam’s 39 not out was not enough on the day, but he gave solid proof of his big-hitting ability, something the format demands.

Sri Lanka’s bowling had been their trump card coming into this tournament, but Hasaranga’s injury following that of Eshan Malinga’s days prior to the tournament have exposed yet another chink in their armour.

Sri Lanka’s batting concerns have also been exacerbated by Hasaranga’s absence. The middle order has struggled for consistency, particularly against spin – a challenge they’re likely to face in abundance against a spin-centric Omani attack – and now one of their better spin hitters is out.

Runs up the order from Pathum Nissanka and Kusal Mendis have been crucial to Sri Lanka’s recent successes, while a revelatory knock from Kamindu Mendis against Ireland has offered hope lower down. But you sense the key to an unlikely upset will be whether Oman can access Sri Lanka’s soft middle cheaply – do that and it’s anybody’s game.

For Oman, this is a quintessential do-or-die fixture. Currently at the bottom of Group B after a loss to Zimbabwe, they must secure a victory to keep their Super Eight hopes alive. They can draw confidence from their warm-up victory over a Sri Lanka A side earlier this month, where Aamir Kaleem’s blistering 80 and Vinayak Shukla’s finishing proved they can compete with the islanders’ second string. They will also need to find a way to contend with the express pair of Dushmantha Chameera and Matheesha Pathirana, having lost nine wickets to Zimbabwe’s seamers in their opener.

Kamindu Mendis wasn’t even supposed to be here. But Sri Lanka are grateful that he is. Picked, dropped, and picked again, Kamindu has never been sure of a place in Sri Lanka’s XI, but a Player-of-the-Match 44 off 19 against Ireland has removed the doubts. Sri Lanka had been crying out for his ability to bat anywhere in the middle order and provide impetus through the middle overs – particularly against spin.

Sri Lanka’s batters struggled to get away Ireland’s modest spin offering at the Khettarama. The pitch in Pallekele might not be as helpful, but recent history has shown that spinners will still play a role. As such, Sri Lanka will need to be particularly wary of Shakeel Ahmed‘s accuracy. He picked up 2 for 24 against the Sri Lanka A side, and if the Pallekele pitch offers any turn, he is the most likely candidate to exploit the co-hosts’ historical struggles against disciplined left-arm spin.

Hasaranga’s injury will test Sri Lanka’s resolve in whether they stick to a 6-5 combination. Hemantha could slot in for Hasaranga, or Sri Lanka might opt for an extra batter.

Sri Lanka (probable):  Pathum Nissanka,  Kamil Mishara,  Kusal Mendis (wk),  Pavan Rathnayake,  Kamindu Mendis, Dasun Shanaka (capt),  Dunith Wellalage,  Dushan Hemantha,  Dushmantha Chameera,  Maheesh Theekshana,  Matheesha Pathirana.

Oman have no injury concerns and are likely to name an unchanged XI.

Oman (probable):  Jatinder Singh (capt),  Aamir Kaleem,  Hammad Mirza,  Wasim Ali,  Karan Sonavale,  Jiten Ramanandi,  Vinayak Shukla (wk),  Sufyan Mehmood,  Nadeem Khan,  Shah Faisal,  Shakeel Ahmed.
