Joe Root is nearing a 150 while Ben Stokes retired hurt himself out to make way for Jamie Smith. With a lead of 130+ runs, wickets are not really an issue and England would want to increase their run rate to make as much run today as possible. They may also play the morning next day before declaring their innings.
This Indian team is somewhat a new experiment as a few of star players are missing from it. It might take them more time to find a balanced team and with the number of options India has, I believe they'll be able to create a stronger team sooner.
Indian bowlers are not able to bowl well on this pitch. England bowlers bowled quite well. Especially Ben Stokes and Archer bowled well. Stoker was able to take 5 wickets and Archer was able to take 3 wickets. But we are not seeing any better bowling from the two experienced Indian pace bowlers Siraj and Bhumrah. England lost their fifth wicket for 499 runs. And the team lost their sixth wicket for 515 runs. England team took a big lead of 158 runs. Probably England will declare the innings after securing a lead of 200+
