New Delhi: The triumph against Bangladesh after a prolonged lean patch has given West Indies the much-needed fillip, but coach Ottis Gibson reckons the Test series against India will pose a different challenge altogether to his young side.

"Obviously there has to be a lot of positives from the Bangladesh series. Guys like Dwayne Bravo, Kirk Edwards and Darren Sammy contributed with the bat and ball, but this is a different challenge," Gibson said.

"India may not be number one now but they are still a top side. India has the better line-up. They have a young side but the experienced guys like Sachin (Tendulkar), (Gautam) Gambhir and (Virender) Sehwag are back," he said, before adding, on a lighter note, "We will probably need to play seven bowlers to get them out."

India lost the number one status post their 0-4 debacle in an away series against England early this year.

What could benefit the West Indies is that they will be playing on conditions, which are pretty similar to Bangladesh.

"We are a team high on confidence. We just played a tough series in Bangladesh where the conditions were similar, so we relied on our skills. We are very well acclimatised to the conditions," the former pacer said.

The mere mention of his fast bowling unit brought a smile on Gibson's face.

"Our fast bowlers—(Darren) Sammy, (Fidel) Edwards and (Ravi) Rampaul -- have been doing well over the past 6-12 months. That's our strength. We hope to quickly make inroads into the Indian line-up. Indian wickets favour spinners and the new ball will not swing for long, so we will need different skills, and one of them is reverse swing."
