Jofra Archer continued his bid to earn a place in England's World Cup squad with a hostile opening spell against Pakistan before rain meant there was no result in Wednesday's first one-day global at The Oval.
But a mouthwatering four-over spell at the Oval during Wednesday's washed out ODI against Pakistan kicked off a new debate about his potential in the Test arena.
But such has been the Sussex paceman's impact, particularly his ability to bowl at 90 miles per hour (145 kmh) without apparent strain, that Vaughan is convinced he should feature in the Ashes, as well as the upcoming 50-over World Cup, even though the Test series does not start until August 1.
When you've sent down more than 25,000 balls in Test cricket in a career spanning more than a decade, you might feel that an uncapped young upstart is the last person you'd look to for advice.
Archer became eligible to play for England this year and earned his first call-up for the limited-overs fixtures before the Cricket World Cup, although he was not included in the preliminary group for the home tournament. In the four overs which he bowled, Archer picked up a wicket giving away just six runs. No England men's team have yet won a one-day World Cup, with the 2010 World Twenty20 their lone International Cricket Council trophy. "He's obviously a class act". He ambles in, bowls 93 miles per hour and makes it look effortless. But Plunkett said: "With him in your squad, you're going to be a better team". Whoever is bowling best should be in the squad. If it wasn't Jofra, someone else would be knocking on the door.
Though England is one of the oldest teams in worldwide cricket history, they haven't won a Cricket World Cup yet. He started with a superb maiden over to Imam, generating movement off the pitch at sharp pace.
"I look back to when I was a kid, you get inspired by big series like World Cups and the Ashes", explained Broad, whose father Chris, an opening batsman, was a key member of the England side that enjoyed a triumphant tour of Australia in 1986/87.
And England's 2005 Ashes-winning captain believes Archer is already a "must pick" against Australia.
"I would be absolutely staggered if he's not taking part in the Ashes series as well as the World Cup", Vaughan told reporters in London on Thursday.
"I've never seen a (England) ODI team go in with the quality this one has got, particularly in the batting, the top seven".
