Kohli and Johnson have had frequent run-ins during the first three matches of the four-Test series, which Australia have already sealed in their favour after winning the first two Tests and the third being a draw.
"It could be quite interesting because they're not known for that aggressive type of play. But ever since I've seen him play cricket, I've always seen him pretty fiery," said Johnson.
Johnson said Kohli's approach hardly changes irrespective of who the opponents are.
"It doesn't matter who he plays against, he plays in your face and that is how he likes to play the game. Virat's just been telling us how many runs he's scored and we've just been saying we're two-nil up in the series so that's pretty much it. It's always been part of the game and always will be," said Johnson.
Except for an influential spell on the final morning of the Gabba Test, Johnson has not been up to the mark so far in the ongoing series against India, and also had to reduce his pace by around 10km/h than what England and South Africa were subjected to. Key to his high speed were the short bursts of around three overs that Michael Clarke kept Johnson fresh for.
