Although James Anderson is regarded among the finest swing bowlers in the business, the England paceman had not enjoyed much success in India.
Every bowler has a country whose pitches he would love to carry with him. Similarly, there are wickets that would rank amongst his least favourite.
Bowling on the flat decks of India can kill a fast bowler's spirit unless reverse swing is a part of your arsenal. Zaheer Khan became potent on these tracks only after he mastered the technique of reverse swing.With the right-arm pacer inducing movement with the new ball and reverse swinging the old ball, he has been brilliant. After ripping the heart out of India's second innings in Kolkata, he has again struck fear in the home batsmen despite the Nagpur wicket not showing much life.
His 12 wicket haul so far in the series also includes Sachin Tendulkar, twice.
"With the kind of form he is in, he will be unplayable," batsman Joe Root had said on Friday.
It took Anderson just three balls to dismiss Virender Sehwag. The ball whizzed in before holding its line as it beat the outside edge and crashed into the middle stump.
Later, with the ball more than 40 overs old, Anderson came around the wicket to Ravindra Jadeja. He managed to reverse the ball into Jadeja's pads, trapping him in front. The wicket added to the late collapse the hosts suffered, keeping England's dream of a series win alive.
"He has phenomenal skill, he has learnt his trade. He is amazing at swing bowling and does it at good pace as well," said batsman Jonathan Trott. "In all, he is very clever, who is a great asset to our side."
After looking listless in the first two Tests in Ahmedabad and Mumbai, the 30-year-old from Lancashire found ways to reverse the ball in Kolkata. In fact, he outshone Zaheer in his own backyard.
On his last tour of India in 2008, he managed only four wickets in two Tests and, in the one day leg, went wicketless in four games.
