Jason Roy is little more than a year into his ODI career but he will be the senior opener as England take on Bangladesh this month. In the absence of Alex Hales, who pulled out of the tour over fears about security, Roy will take to the field alongside a new partner, beginning with England's first warm-up match in Fatullah on Tuesday.
Roy has opened with Hales in 27 of his 29 innings, building an impressive record together since the 2015 World Cup. The hugely impressive but uncapped Ben Duckett has been tipped to take Hales' place, although England appear to be considering a return to the top of the order for Moeen Ali.
"Whoever comes in deserves a go," Roy said. "They are going to get a huge opportunity to state their mark on international cricket. Whether it's Duckett or Moeen, I've been batting with a few of the guys, I don't know yet - I just get on with it. We get on that well we don't need to worry.
"Joining up with the boys now, been away for a couple of weeks, it's straight back in. We have great team cohesion. I won't think of myself as the senior partner - we are all equal, just crack on and maybe try help whoever it is out. If it is the new man Duckett, he might be nervous, but he deserves to be here."
Moeen has only opened once in ODIs since the World Cup, when Hales hurt his back in the field against Sri Lanka at The Oval earlier this year. If he is asked to open, that could leave Duckett competing with James Vince for a spot at No. 3.
Roy is among a handful of batsmen to have scored 1000-plus ODI runs at a 100-plus strike rate and he said that he will try to bat the way he has so far in his short career, in which he has found early success. He said he considers himself far from being the finished product as an international batsman and is focused on developing himself as a consistent match-winner.
"I still have lots of work to do, loads more runs, a few more hundreds," Roy said. "I don't really settle for mediocrity. I don't know if that's a good thing or not. I want to improve and win more games for England but I'm pretty happy with where my game is. I've matured playing in big games.
"I probably won't change my approach mentally, but maybe a couple of things technically. Really it's all very similar, trying to get the team off to a good start - the first 15-20 balls are going to be huge, getting myself in. Like I said, we have just had one real net session today so we will assess how the game goes tomorrow and go from there."
Roy said that the hot and humid conditions in Bangladesh - the temperature was around 33C in Mirpur on Monday, with 75% humidity - will need some time to get acclimatised, but he hopes to be prepared for the first ODI on Friday. Roy suffered a dizzy spell in a game against Pakistan in August and will know the importance of taking on fluids.
"You don't really think about it too much," he said. "You've just got to get on with your job. It can be draining but that's what training days and practice matches are for, so that when we come to Friday we are ready.
"You don't realise how much you are sweating and the next minute you can feel a bit weird. Concentration will be key, just keeping yourself ticking over and batting for as long as possible."
