In-form fast bowler Mohammed Shami feels that variation in length will be the key to keep the Bangladesh batsmen on their toes as India play their first-ever pink-ball Test at Eden Gardens, Kolkata starting Friday.

Shami wrecked the Bangladesh batting lineup taking seven wickets in the Indore Test. The 29-year-old has the best strike rate in the world in the last two years and rose to his career-best rankings ahead of the historic Test.

“What one thing bowlers should do is keep an eye on the wicket and how is it behaving, so what I do is as the pitch gets slower I keep pushing myself and when I notice that the batsman is uncomfortable I go over the top… so the length has to keep changing,” Shami said on a talk show on Star Sports.

Meanwhile, former India skipper Sunil Gavaskar had a piece of advice for India’s in-form opener Mayank Agarwal, who was named ‘Man of the Match’ for his second Test double ton.

“He is enjoying Test cricket, this is his first year and hopefully he keeps scoring on the second year also because in the second season there is a lot more data available of you to the opposition.

“But he has been batting beautifully, the way he balances himself without falling on the offside as he plays so straight and his movement of the front and back foot has been fantastic making him the man in form who is full of confidence,” Gavaskar said.

Former India cricketer Gautam Gambhir is impressed with Indian bowlers including the ones in the squad and the ones injured and waiting for their turn.

“If you see other oppositions, some teams have got quality fast bowling attacks, some have quality spinners but if you look at this Indian side, they’ve got two quality spinners, three quality seamers plus Jasprit Bumrah and Bhuvneshwar Kumar who are not in the playing 11.

“So they’ve got proper 5 seamers plus Kuldeep Yadav which makes it 8 quality bowlers all capable of running through batting line-ups and that is why the Indian side has been able to take so many all-outs in the last 2 years.”
