Old Trafford will play host to the World Cup's biggest mismatch, on paper at least, with hosts and world number ones England taking on an Afghanistan side who sit 10th in the rankings.
Little that has happened since the tournament began points towards an upset, with England boasting three wins from four and Afghanistan the only side yet to register a point.
Bangladesh's victory over the West Indies at Taunton was a minor upset to some but a reversal of the form book in Manchester would be a shock of the top order.
Afghan optimism will have been raised by the injury absence of Jason Roy, but England skipper Eoin Morgan is expected to play after back trouble.
World Cup snapshot
Tweet of the day
Tigers fans added a welcome splash of colour to the stands, making a little corner of Somerset their own for the day.
One to watch
James Vince expected to be lining up for Hampshire instead of taking part in England's bid to make history on home soil. Alex Hales' indiscretions opened up a place in the squad and Roy's injury has now created a vacancy at the top of the order. With a top score of 51 in his 10 caps to date, now would be an ideal time for Vince to announce himself.

Data point
The Afghanistan leg-spinner has been the most prolific ODI wicket-taker of all since the 2015 World Cup, taking a scalp every 24 balls. He has proved less effective in England, though, with his strike-rate soaring.

New Zealand v South Africa, Edgbaston (Jun 19).
