Andre Villas-Boas will only return to management with a club that has a clear vision for their future, according to his agent Carlos Goncalves.
The 34-year-old boss has been out of work since March when he parted company with Chelsea following a testing period in charge.
He is presently being linked with the coaching positions at Liverpool and Roma.
However, his adviser believes the former Porto coach will only return to a club that will provide an environment where he can flourish.
Asked about the rumours linking Villas-Boas with Liverpool and Roma, Goncalves answered on romagiallorossa.com: "Liverpool and Roma? Well, what we are looking for is a [club with a] strong technical plan, that is solid and durable.
"Villas-Boas would like to return to coaching in these conditions, but if these conditions are not available, we would have no problems not working.
"I won't confirm or deny contacts with specific clubs. What we are interested in is a technical project, its outlook and a situation that has longevity."
