West Indies batsman Ramnaresh Sarwan has asked his team to "stay positive" against Harbhajan Singh during the ODI series.

Describing Harbhajan as an important performer for India, Sarwan said his team will have to click as a unit as they tackle the Indian bowling attack in the four-match series, beginning on Friday.

"We've got experience and hopefully we'll come together as a unit. Over the years, we've tried to rotate the strike as much as we can, but we know how good Harbhajan Singh is and he's been a very good performer for India over the years," Sarwan said.

The Guyanese felt the key to his side's success in the series beginning at Sabina Park, would be how well it could work on the ball.

"It's important that (the West Indies) stay positive against him as well and the rest of the bowlers that we'll be playing against, but I think the key when we play India is to try and work the ball as much as we can," he said.

Sarwan also felt that irrespective of their recent Super-Eight match win over India in the ICC World Twenty20 in England, Indians will be "a handful in the Caribbean".
