The bowlers gave it their all to get 20 wickets: Dhoni

India captain Mahendra Singh Dhoni on Wednesday 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 on 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.

"The ball was getting old and the wicket was getting slower and slower. This is a reason we decided to bowl first on this wicket. If you bat first you need to score 600 plus or else you have to again come and bat. So it was tough but I think the bowlers did a terrific job," Dhoni said.

Bowling a long spell, Zaheer was at his best on Wednesday, decimating the hosts with his seven for 87 in the second innings.

Heaping praise on the left-arm seamer, Dhoni said, "The ball was old and it was getting reverse swing. It was also keeping low. So we felt we can get some LBW decisions in our favour and decided to give Zaheer a longer spell."

Also praising left-arm spinner Pragyan Ojha for chipping in with two second innings wicket, Dhoni said, "Credit also goes to Ojha who took that one wicket of (Mohd) Ashraful at that time."

Dhoni was elated after the team's convincing series win but he refused to be complacent.

"We always can do better. For the last 12 months we have done well in both ODIs and Tests. There is always scope for improvement but the result is very satisfactory," he said.

However, Dhoni sounded a bit worried about the number of injuries that has haunted the side in this series.

"The series was full of injuries so I am a bit worried. But with the amount of cricket that we play these days, it is ok. I hope the players (VVS Laxman and Yuvraj Singh) are fit before the South Africa series," he said.
