Trivia This isn't the first time a team has chased down a target without any of their batsmen scoring a run. It has happened at least once before, when a no-ball from Syed Kirmani gave West Indies a win in Barbados in 1983.
Post-match presentation: Sachin Tendulkar gets a memento for becoming the first batsman to score 13,000 Test runs.
Zaheer is the Man of the Match for his ten-wicket haul.
Shakib: "We didn't bat two hours well, that's why we lost - first hour in the first innings, and an hour before lunch today. Everytime someone is getting runs, but we need two or three guys to score in each innings, that's something that we have to improve."
Zaheer is also the Man of the Series. "Particularly this match it was tough for the bowlers as the pitch kept getting slow and low, but once it started to reverse there was something in it for the bowlers.
"Still long way to go (to reach his best), still working on my fitness, this particular spell is a confidence-booster for me."
MS Dhoni collects the series trophy. "It was a difficult task to get 10 wickets in the second innings as there was nothing in the pitch to help either the fast bowlers or the spinners, that's one of the reasons we were keen to bowl first.
Zaheer's spell was remarkable as I feel it was a fantastic wicket to bat on.
"We were looking for the new ball, but with the ball keeping low we wanted to see what the fast bowlers could do with the ball reversing, credit goes to Ojha as well as he got the wicket of Ashraful after which we decided to not go for the new ball."
Dhoni's record of never losing a Test as captain remains, but it is something that will be tested in the matches against South Africa next month.

Bangladesh's final seven wickets went down for 22 runs, undoing all the good work of the top order. India, though, will be thrilled their injury-riddled batting line-up hasn't be asked to do much in the final innings. Zaheer becomes the fourth Indian fast bowler to take ten wickets in a match away from home.
that's it, India need two to win, Zaheer gets ten in a match, the batsman plays down the wrong line to a length delivery which knocks over offstump
shortish ball, just outside off, batsman sways outside the line
starts with a delivery bowled from wide of the crease, on the pads and rolls towards the leg side
Zaheer's career-best effort has put Bangladesh on the brink of a heavy defeat. It was all so different at the drinks break, when Mohammad Ashraful and Shahadat Hossain made India toil and Bangladesh were looking to set a tall target. It was the Indian spinners who started the collapse, slowing their pace and giving the ball more air, to take three quick wickets.
Join us at 12.10 to see whether Zaheer can complete his ten-wicket haul.
