Ex-Swansea boss Molby believes the 47-year-old has yet to achieve his full potential but thinks an opportunity at the Liberty Stadium could be the opening he has been looking for.
“If you look at his CV, he did very well with Brondby with a young group of players, got them playing the right way,” Molby told BBC Sport Wales.
“Moscow, I think he just landed in a country where it was impossible with language difficulties, they just didn’t allow him to do what he wants to.
“And from the moment he set foot in Mallorca they were just beset with financial problems that he never quite got over.
“This is the opportunity now, he has to make a mark as a manager.”
