If I were in charge of England,
1. Keep Butler (too risky giving JB the gloves - may affect his batting), BUT tell him to play like a t20. Innovate and play some unorthodox shots vs the spinners (Sarfraz Ahmed did this to completely neutralize Herath vs SL)
2. Everyone else needs to graft his innings - learn from Cook, Root and Rashid
3. Have Ian Bell open with Cook (its a quick fix, but Ali is just no good up there)
4. Consider dropping Rashid for Samit, or a pacer - he's currently not good enough to trouble Pak (Abu Dhabi was aberration - Pakistan basically self destructed...won't happen again).
