This might sound crazy or OTT but would it better if England could get rid of Jennings or Malan and induct a right hander to counter Ashwin. England's top 6 includes 4left handers. You obviously cannot drop Cook and Stokes. One of jennings and malan has to go. Otherwise Ashwin will just run through them. I can visualize cook and Jennings getting bowled or lbw to him early in the innings.
