The former Pompey boss explained that he spoke to the club after Mark Wotte was dismissed in 2009.
"That was a few years ago, when Markus Liebherr took over the club, and I was interviewed," said the 47-year-old to the Daily Echo.
"It was quite understandable. They got Alan (Pardew), who's a good guy, and the rest is history.
"It's a super club, with great facilities.
"My great friends, Les Reed and Martin Hunter, are down there at the moment doing some brilliant things.
"It's a club that deserves a lot of success."
