Martinez has impressed for Catania this season and have been linked with clubs around Europe.
“Many Italian clubs have expressed an interest in Jorge, but the only negotiation at the moment is with Manchester City,” Daniel Delgado told calciomercato.it.
“There is also another English team seriously interested.
“We’re talking about a player who can play in four or five positions and I don’t understand why more top Italian clubs have not taken note.
“We have all seen what he did to Inter, but I fear once again Italy is ignoring a great player.
“He would like to stay in Italy with a top team, but at the moment it is more likely he will go to England.”
