Joe Root demanded England be more ruthless and promised improvements after a 157-run defeat on Monday handed India a 2-1 series lead with one Test to go. 

The tourists' five-man attack shone on day five to collect their first win at The Oval since 1971, Jasprit Bumrah impressing as he became the quickest India paceman to 100 wickets in the longest format. 

After Rory Burns and Haseeb Hameed shared England's first 100-run opening stand in the fourth innings since October 2016, Virat Kohli's bowlers ran riot as the hosts collapsed, losing six wickets for 47 runs. 

Bumrah and Shardul Thakur, whose first-innings half-century was the fastest in Test cricket in England, provided the impetus for India and Root pointed to the former as an example. 

"You look at this game, it's been frustrating today to lose 10 wickets," Root said post-match. 

"But I think, when you look where the game was lost, we should have got a bigger lead first time around with the bat. It would have been nice to have another 100 runs and then we're looking at a completely different game. 

"We have to be a bit more ruthless, with the first-innings runs costing us there. And with our catching, we did put down a few chances. Some were extremely difficult but when you give chances and half-chances to world-class players, they take them. 

"You look at that spell from Bumrah, he recognised the key moment in the game and turned it on its head. It's something we have to look at doing ourselves." 

Indeed, Bumrah has taken the second-most wickets in the series (18) behind Ollie Robinson (21), with England the 27-year-old's favourite opponents, striking 36 times at an average of 24.08. 

And it was his afternoon spell, coupled with Thakur's dismissal of Root, that got the ball rolling for Kohli's men. 

"I think it's something we have to get better at and keep looking to improve, recognising those key moments in games and forcing things a little bit more," Root continued. 

"We did it very well at Headingley but here we did not manage that and it's something we have to be more consistent with, looking at certain situations and getting us into that advantageous position. 

"It's hard to take but you have to look at how he responded from Lords to Headingley and we will look to do exactly the same at Old Trafford. We're more than capable of turning things around very quickly."
