"If they do not participate in the Champions Trophy, it is going to be a big loss because India has a huge cricket followers in the world. Hence, it is not going to be great for stakeholders," Miller told PTI in an exclusive interview here.
Amla added: "If India pulls out, it will be a huge loss for Champions Trophy getting exposure. If somebody wants to see an exciting Champions Trophy, then all eight top teams in the world should be participating."
"Which team will come in as replacement for India, I do not know. Nor do I know what they are going to do," he said.
Doubts of India's participation in Champions Trophy came to the fore after BCCI missed the April 25 deadline set for announcing the squad for the Champions Trophy.
The BCCI, who has been at loggerheads with the ICC on the proposed revenue model which considerably cuts down India's share, issued a threat of pulling out of the Champions Trophy.
