Lazio could target Mattia Cassani of Palermo after their move for Genoa's Abdoulay Konko stalled.
The Biancocelesti are looking for a new right-back as they are on the verge of selling Stephan Lichtsteiner to Juventus.
Konko was their preferred replacement for the Swiss international, but they have hit problems in their attempted swoop.
Although an agreement with Genoa over a transfer fee has been agreed, personal terms crucially haven't with the Marassi player.
As a result, Lazio could instead make a move for Italian international Cassani this summer.
Palermo President Maurizio Zamparini recently admitted that the player may be "fed up" of the Rosanero, but added that nobody had made a serious bid for his services.
Meanwhile, some reports claim that Lichtsteiner's switch from Rome to Turin could be completed over the weekend.
