Paceman Steve Finn says England's tenacity helped leave them on the brink of a crushing victory in the third Test in India.
The hosts cruised to 86-0, but Graeme Swann bowled Virender Sehwag and 36 runs later, five more Indian batsmen had returned to the pavilion after a relentless spell in Kolkata.
Although an unbeaten 83 by Ravichandran Ashwin provided some spirited resistance, India only have a lead of 32 runs with one wicket remaining with England sniffing a 2-1 lead in the four-Test series.
After snaring three wickets for 37 runs, Finn proved a menace with the ball on a flat wicket and the bowler told Sky Sports: "I thought we worked hard.
"It was hard for us to get that first wicket but we stuck to our guns and we stuck to the plans we have worked towards in the series and that paid off.
"At lunch we said that we needed to up it a bit. We needed to focus on how we wanted to get the batsmen out.
"We got lucky with the run out and we had a very good ball first up after lunch."
The 23-year-old Middlesex star grabbed the key wickets of Gautam Gambhir and Virat Kohli before reverse swing came into play, aiding the downfall of Zaheer Khan with a leg before.
Asked about his late swing, Finn added: "That is something I like doing. When you come out here it is something that you have to be able to do.
"It's a good weapon for us to have. It has done it more here than at the other grounds because the wicket is more abrasive."
