When asked about Kohli's lack of respect comments made yesterday, Warner replied, "That's his opinion as he had got 160-odd runs. So let him say what he wants to say. Whether it's the right thing to say or not, it's up to him. There is a line you cannot cross and it is for the ICC to manage with their fines and warnings. When we talk about sledging and stuff, physical contact and verbal swearing is where we draw the line."
