I think this England performance - and result - is a massive feat considering the way they faltered at Lord's. It's pretty typical that a few star players carried them over the line (Cook, Root) but the best sides have always been reliant on one or two talismanic figures, to be honest.*
They rebounded exceptionally after the way they lost at Lord's, but were obviously boosted by the returns of Jimmy Anderson and Stokes.
If Stokes is injured, it seems to me the selectors have one of two options: Finn comes back in in the hope he plays himself into some form, or Rashid is deployed.
For what it's worth, while Moeen is struggling to impress still, it's worth remembering he boasts the third best strike rate of any English offspinner since the War. Only Swann and Jim Laker boast better figures.
