India will be playing in different and challenging conditions in South Africa next year. The Virat Kohli-led team India have to perform like the number 1 team, that they are, according to Gautam Gambhir.

Former India opener feels that being the world's No.1 Test side, India should win in "every condition". Starting January 5, India will play three Tests in South Africa against the world's No. 2 side, besides six ODIs and three Twenty20 Internationals.

"It's going to be a tough tour because South Africa is a very good side, especially in their own backyard. They have got quality bowling, they have got quality batting. India really has to play well to beat them," Gambhir said on Wednesday.

The veteran batsman feels their recent performance will give the Indian team some confidence. Gambhir hopes India delivers the same what they delivered in India.

"I hope they have got the confidence from what they have done in the last two years. Even if they have played the bulk of their cricket at home, they should go to South Africa with a lot of confidence, a lot of belief as the No. 1 Test side and I hope they can deliver there.

"Ultimately, the No. 1 side should be able to win in every condition. I hope India continues the same form what they have shown at home," he added.

Post South Africa, India will also travel to England and Australia next year. The conditions will be less assisting to the spinners and that will check India's ability to adapt.

However, they have some quality pacers on their side who can play a vital role in their victory.
