Catania are drawing up a list of alternatives should Diego Simeone choose to leave in the summer after barely six months in Sicily.
Simeone's appointment hasn't met with expectations and there are reports that his contract might be terminated on a mutual basis.
Catania aren't yet safe in Serie A and risk relegation with four games of the season remaining.
Il Corriere dello Sport understands Catania would consider bringing back either Walter Zenga or Pasquale Marino for a second stint at the Massimino.
Surprisingly, though, Sinisa Mihajlovic's assistant Dario Marcolin is said to be at the top of Pietro Lo Monaco's shortlist for the job.
