The 22-year-old is currently on loan at Championship Bolton but Clarke is adamant he has a part to play at Albion.
Clarke said: "We know what we've got in Craig. His future is here. I said that when he went out on loan and I will repeat that.
"His future is here and nothing has changed. We sent him out to Bolton to get games and experience under his belt which is what he needs.
"But we have to make sure Craig and Gabriel (Tamas) get enough games so they're ready to step in as and when required."
Clarke added: "We're pleased Craig chose Bolton because it's a good club and he can learn there.
"It was important he went somewhere where they try to play the right way.
"He has a never-say-die attitude and great character and his all-round game will improve as a result of playing matches."
