Virat Kohli shocked one and all a week back when he announced his resignation as India’s Test captain.

While fans and plaudits from across the world reacted, the ex-South African pacer has finally broken his silence on the subject.

As per Steyn, he reckons Kohli took this step because of bio-bubbles and to be there for his family.

Steyn said Kohli's decision probably had a lot to do with demands of staying away from family for a long duration inside a bio-bubble.

“Maybe these bio-bubbles and all had a role in it. I mean it really boils down to family for somebody like Virat. He’s got a young family right now,” Steyn said.

Steyn said, the pressure of captaining a side like India can become tougher as you start reaching a certain point in your career.

Under Kohli's leadership, India have reached many highs including achieving the No.1 ranking and staying on top of the table for quite some time
