India captain Mahendra Singh Dhoni today singled out star performer Zaheer Khan for the team's series victory and said the bowlers did an excellent job on an unresponsive track in the second Test against Bangladesh.

"It was a difficult task to get wickets in this track, both for spinners and pacers. But all credit goes to the bowlers. They really put their best to get those 20 wickets, especially Zaheer's spell," Dhoni said after his team crushed the hosts by 10 wickets to clinch the series 2-0.
