There could be some argy-bargy in the West Midlands derby - because Clarke says the two Scottish bosses are so passionate about the game.
Clarke said: "I've not had any tussles with anyone yet, but you never know - it's a local derby.
"Maybe we'll show our passion in different ways but we'll both be passionate.
"Some managers make comments, some managers don't.
"Some managers jump around on the touchline and others don't. We all just have our own way of dealing with it. If Paul wants to jump up and down on Sunday, I've got no problem with that."
