India captain Mahendra Singh Dhoni says that if his side stick to the basics, preserving their number one Test ranking will take care of itself. Dhoni’s team, also the 50-over world champions, have topped the ICC’s Test table for more than a year but could be knocked off their perch if England, currently third, win the upcoming four-match series by two clear victories. India, who completed a 1-0 win in a three-Test series away to the West Indies on Sunday, have just one warm-up match — a three-day fixture against Somerset starting here on Friday — before facing England at Lord’s next week.
