"I remember a few years back, in the last tour in 2007, Zaheer did get a lot of reverse swing. That's when I started practising it. There is a shiny side, and if the batsman knows which side it is, it makes it a lot easier for them. It proved to be a good skill," Anderson, who got three wickets including Virat Kohli and Sachin Tendulkar told the mediapersons.
Asked about the reverse swing, he said:"We had hints of it in the last two matches. I saw the pitch and said let's go ahead. Reverse swing is crucial for seam bowlers because it keeps you in the game. I felt pretty good whole day. I think I bowled reasonably well with the new ball first thing. And enjoyed it as much as I could."
Anderson is one of those bowlers in world cricket who has got a brilliant success-rate against Sachin Tendulkar having dismissed him around eight times in longer version.
"It's always good to get Sachin's wicket. Once I retire, it will be nice to tell others that Sachin's was a big wicket. When I got him out, it looked like he was set. He was bit scratchy to start with but was happy to get him out when I did."
Asked about the Jonathon Trott low catch that dismissed Gambhir, he said:"Really difficult to field in the slips and hold onto these low catches. Luckily, he caught onto it in the end."
The seamer seemed happy with the Eden Gardens' 22-yard strip.
"This pitch is very abrasive. Reverse swing is a tricky art to practise. But we were able to swing the ball. There is a bit of dew because of the early start and that helps."
