England captain Alastair Cook admitted that his side was "outplayed" by India in the first ODI here but insisted that the visitors have the self belief to come back strongly in the five-match cricket series.

After posting a challenging 300 for seven, India shot out England for 174 in 36.1 overs to register a comprehensive 126-run win at the Rajiv Gandhi International stadium on Friday.

"We were outplayed in all three departments. We gave away around 180 runs in the last 20 overs and I think that was 30-40 runs more than what we had expected to restrict them to. We were also unusually sloppy in the field," Cook told the reporters at the post match media conference.

However, the England skipper says that one defeat can't dent the "self belief" of his boys and they will come back stronger.He didn't forget to mention that losing the toss also proved to be a key factor in these conditions.

"It was an important toss to win, we saw at the end that the ball kept low. We're going to have to learn from this, and that's the beauty of a five-match series."

About his team's inability to play spin bowling, he confessed that's an "issue."

"We know that (playing spin) is an issue, and that's a skill thing. We're going to work hard on that in the next couple of days," the skipper added.
