Shamshuddin was not originally listed to stand in the match, as per the International Cricket Council’s schedule, but found himself in the eye of the storm when he gave an incredulous Root out leg before with just eight runs needed from the final over.
Earlier in the game, the 46-year-old had raised eyebrows by giving Virat Kohli not out to a clear lbw.
Root was visibly annoyed at his dismissal and assistant coach Paul Farbrace appeared to share a couple of choice words with the official when the sides shook hands following a dramatic finish, which set up a winner-takes-all shootout in Bangalore on Wednesday.
The mood in the away dressing room would have been considerably better had they managed to get over the line without Root but Jasprit Bumrah closed out an engrossing match in style with some magnificent death bowling.
England captain Eoin Morgan, bristling in the post-match conference, said of Root’s departure: “There is extreme frustration, absolutely.
“It shifted momentum, first ball of the 20th over. Losing a batsman who’s faced 40 balls on a wicket that’s not that easy to time it on is quite a bit of a hammer blow. It’s proved very costly all things considered.”
Asked if England would take their observations to the International Cricket Council, or match referee Andy Pycroft, he added: “Absolutely. We have an opportunity to do before the next game.
“It’s part and parcel of the job, to be able to cope with the pressure and make good decisions more often than not.
“The fact that comes out of today’s game as a highlight is disappointing, it shouldn’t be like that. It should be a good performance by both teams and a really competitive game.
“But we will draw a line under it tonight and move on to think about what we may come up against in Bangalore.”
