Eoin Morgan insists England will have no hesitation in changing their winning combination ahead of the 2019 ICC Cricket World Cup.

The tournament favourites are unbeaten in their last ten bilateral ODI series and sit as the No.1 ranked side in the 50-over format, based largely on an unchanged and balanced bowling line-up.

But the emergence of Barbados-born Jofra Archer has complicated selection matters with just over two months to go until the opening match against South Africa.

Archer, who qualified to play for England earlier this month after the ECB relaxed its residency rules, has exploded onto the world scene with extraordinary performances in limited overs competitions.

And Morgan refused to shut the door on the 23-year-old's World Cup hopes – despite his selection potentially rewriting plans that are two years in the making.

“It’s not about a winning formula,” said England’s limited overs captain Morgan, who welcomed fans to the first Super Saturday of the ICC Cricket World Cup Trophy Tour, driven by Nissan, in Manchester’s Exchange Square.

“That is behind us almost and we need to continue using the confidence we have earned to drive things forward and if it is about including someone that’s going to add value then we’ll do it.

“The hype about Jofra playing around the world and doing well and attracting a lot of attention is justified as he has put in performances that warrant looking at.

“[Coach] Trevor Bayliss said after the West Indies series we will look at him against Pakistan [who England play in five warm-up matches in May] and that’s what we will do.

“We don’t have to name our squad until the end of the Pakistan series so we’ll have a look and see how he goes.”
