My take is that Rohit ,Pujara and Virat will step aside OR be forced out of the Test side. The transition has to begin soon. Rahane- I'll still hold onto to him, for the fact that he might end up performing the role Kumble did for India in 2008. Ashwin could also be a stop-gap skipper till they hand over the reigns finally to Iyer.
Jadeja has proven time and again that he can only perform on track that assist him. India will have to look at alternatives and might be even willing to look at Bishnoi, who has been nothing short of a revelation. With the considerable lack of India A/B tours, it is increasingly difficult to spot all-round talent, unless you go the IPL way and blood in somebody(not recommended at a Test level)
The bowling-again- not too happy with the erratic lengths from our bowlers in the 1st innings. Much was expected of Shami, but it wasnt to be. Umesh should be on his way out now.
For the WI series- I would ideally wait until the CWC Qualifiers to figure whether they'll play in the World Cup or not. If not, I wouldn't send our team there. With the financial clout that we have, we can very well stage an ODI tri-series with England, Australia New Zealand. Anyhow ,since the context is w.r.t the transition and WI series, I would really like to see the likes of Gaikwad, Sarfaraz in the side and hopefully these guys get a longer run.
P.S: Bumrah and Pant are finished IMO. The worst thing that the Indian management can do is to induct either into the World Cup squad. Their past exploits have been great- however, all of that came in a younger, fitter body. To be eligible for the Indian team, they need to go back to the grind, sweat it out in domestic and then return. There can be no substitute. India learnt this lesson the hard way in WT 2021, where we trailed a variety of players before the tournament. However, the main tournament saw the return of demi-Gods, who didnt perform on their given day.
