Virat went for an improbable win at Adelaide, 4 years ago (and almost got it but couldn't mainly due to rigid and unreasonable stand against DRS from the original captain of that tour). I'm a die-hard fan of him since then. In the next 4 years, many times he indicated, test cricket (specially against SENA countries) is his priority than anything else.
Not surprised at all, when he ranked this series win above WC wins.
