Tests vs India Will be Tough, But We Are No. 1: Faf du Plessis

India and South Africa have begun preparation for the first Test in Mohali from November 5. South Africa, who have won both the T20 and ODI series against MS Dhoni's India, may be confident but know the challenges against India who have the better spinners and difficult to beat at home. India will be captained by Virat Kohli.
