India appear highly likely to secure a series-clinching victory in Mumbai on Monday, but James Anderson says England's only option is to come out with a positive approach as they seek to upset the odds.
Virat Kohli and Jayant Yadav compiled 235 and 104 respectively on day four and shared a mammoth eighth-wicket stand of 241 as the hosts - 2-0 up in the five-match rubber - racked up 631 all out to seize command of the fourth Test.
Although Joe Root (77) and Jonny Bairstow (50 not out) displayed admirable resistance for England, the tourists will begin the final day on 182-6, still 49 runs short of making their opponents bat again.
However, with a draw of no use to England as they aim to stay alive in the series, Anderson told BBC Sport: "We've got to be positive."
The veteran seamer added: "There's no point trying to bat for a draw in this game. We've got to try and win the game somehow, try and get something to bowl at on a pitch that, as we've seen, is turning a lot.
"You never know what can happen in this game. Every run is crucial."
In an interview with Sky Sports, Anderson acknowledged the supreme form of Kohli, who now boasts a record-breaking 640 runs in the series.
"We had success against him in England but I think the pace of the pitches over here take any of the flaws he has got out of the equation," said England's record Test wicket-taker of the India captain.
"You try and stay patient to him, he stays patient, and obviously he plays spin very well. Pitches like this suit him down to the ground.
"It was obviously a tough day for us. We came here this morning thinking if we can get those three wickets quite quickly we're still in the game.
"Unfortunately that didn't happen. It was probably our worst morning on the whole tour from a bowling point of view. They got away from us a little bit early on."
