I think lot of things went wrong for England - the most important one was England's batting was below par. So many posts about Ali, Rashid, Woakes and England's bowling combination etc etc but not many about dismal batting performance by Cook, Root etc. They never got a big score to set an example and motivate other batters.
England won the toss thrice and never secured a lead. Batting in India is different - its easiest in first session of day 1 and keeps getting harder as match progresses unlike other places where its harder on day one then gets easy and the gets harder again.
India has similar problems when they travel, batsmen dont score enough. You need runs on the board to put the opposition under pressure which also helps bowlers to attack more and get 20 wickets.
And atleast this series will put the "win toss win the match" western myth to rest.
