England vs West Indies LIVE: T20 World Cup latest score and updates

And Roy immediately takes the opportunity to nudge one wide of the bowler and trot through for a single to that long-on fielder.

Nearly! Roy scurries down to try and prevent Rampaul setting into his length and is squared up by some away nip, the ball tumbling just short of backward point having taken a thick outside edge. That prompts a fielding change from Kieron Pollard - third man is beckoned inside the circle with mid-on pushed back to the boundary.

To open at the other end will be the experienced Ravi Rampaul, rejuvenated and back amongst things in a West Indies shirt after a strong CPL. Can he cause Roy and Buttler some bother?

Buttler tries to repeat the shot but this time finds mid-off, before blocking Hosein’s inswinging arm ball off the back foot to close the first set of six.

England ahead of the required rate, if you were wondering.

Gorgeous! Hosein tosses one up for the first time and Buttler wastes little time caressing him through the covers for the first boundary of England’s chase.

Good from Hosein, finding a bit of early movement through the air with an upright seam that nearly hurries Roy and forces the England opener to drag his toes out of the path of the ball. Eventually it is punched quite nicely to long-on to get the scoring underway.

Hosein saunters up to the crease from a distance and Jason Roy is confidently forward, driving to short extra cover, who fields to his right with a stoop.

Jason Roy and Jos Buttler shadow-bat as they make their first strides out to the middle, settling into a slow wander as they have a final chat, bats dragged along at their sides. Chris Gayle practices some off-breaks - I’m not sure he’ll be required, but he is the West Indies’ second spin option.

It will be Akeal Hosein to start, unsurprisingly, and Roy to face - he has spoken about liking to take strike even if the match-up suggests it should be Buttler. 56 to be hauled in, and the West Indies have Kieron Pollard at short leg (!) and Gayle at slip.

No. Almost certainly not. England will be eyeing a big net run rate boost, you’d think.

But what might the West Indies try to put the cat amongst the pigeons? They could well start with spin - Akeal Hosein bowls regularly with the new ball for the Trinbago Knight Riders in the Caribbean Premier League and matches up well with Jason Roy who will almost certainly take strike.

If they do get Roy early, England might be tempted to then go to either Jonny Bairstow or Moeen Ali, their two best hitters of spin, to negate further threat from Hosein, but it is an excellent chance for a red-inker for those in the top order - the run rate won’t be a problem, obviously.

For a side that has assembled perhaps the most feared batting unit in Twenty20 cricket history, that was staggeringly bad from the West Indies. There was little change of approach having been knocked back early and they have been swiftly extinguished, completely unable to reset after those powerplay wickets. If the pitches remain bowler-friendly this could become a tournament of grinding out defendable scores in the manner that South Africa did earlier, and the West Indies really failed to adapt.

As for England, that was a study in the excellence of execution. Every plan was carried out perfectly and worked exactly as Chris Silverwood, Eoin Morgan and the strategists would have hoped. “A masterclass,” says Nasser Hussain, and it is impossible to disagree.
