Billigs has the ability to win matches with ease - but he needs to develop enough to play each ball, and not try to destroy everything.
Buttler is as destructive as either Billings and Morgan but needs to find his form in the next couple of matches.
If England could rely on Ali every match (in other words, if he bowled the same kind of quality as he did today in every game) then imagine replacing Rashid with Bairstow/Hales or another batsman!
Although to be honest, the batting line up still looked extremely strong with Rashid!!
But anyway, I suspect India will bounce back strongly - so tougher tests to follow in the next two matches!!
