Former Toon midfielder Clark told the Evening Chronicle: "We're back to where we were in the early 1990s now, and then Kevin Keegan built something up that could last for a long period of time.
"Alan is the man to get that up and running. It's about rebuilding and getting an infrastructure."
Clark hopes that he will be pitting his wits against his old pal in a pre-season friendly next month.
Now boss of Huddersfield, Clark takes on his old side Newcastle on July 21.
He said: "I hope that Alan will be in the opposite dugout and the situation is rectified.
"I will say it again - he is the only man for the job, and at the moment that's what the club need if they want to get back to the Premier League."
