Historically, England have tended to produce orthodox bowlers, rather than those with unique traits that are so essential in white-ball cricket. The excitement around Mousley reflects how he gives England a bowler with a distinctive threat. International batsmen will face tens of thousands of deliveries in their careers; they will probably not face anyone who resembles Mousley, a curious hybrid of spin and seam.

“It’s a different skill – it’s probably not traditional off-spin,” Mousley said. “It’s one of those things which I’ve just learnt to bring into my favour and it’s OK to be different as a bowler. I play on small boundaries at Edgbaston and a big boundary one side, you have to learn to adapt.

“They say off-spinners can’t bowl at right-handers but I don’t believe in that, I made it clear at Warwickshire I didn’t believe in that and then ended up getting a bit of confidence. It went from there.”

Growing up in Nether Whitacre, a village north-east of Birmingham, there have been two sporting constants in Mousley’s life: playing cricket and watching Aston Villa, where he has had a season ticket since the age of three. He counts seeing the win over Bayern Munich this year among his most cherished memories.

That list might soon need updating. Over the weekend at Kensington Oval, Mousley’s parents sat next to Jacob Bethell’s. At Warwickshire, the two all-rounders, who both bat left-handed and bowl spin, have become close friends, rising in tandem: aged 23, Mousley is two years older than Bethell. In Barbados, Bethell’s 58 not out was crucial to England’s win on Saturday; Mousley’s two for 29 from four overs then helped them to victory on Sunday.
