Giampaolo Pazzini and Houssine Kharja could make their Inter debut on Sunday against Palermo, as they are in Leonardo's squad.
The players arrived this weekend from Sampdoria and Genoa respectively and are thrown right in at the deep end.
There are even some reports that Pazzini could start at San Siro in the Serie A Week 22 clash.
Leonardo has more options at his disposal, though, as Diego Milito, Philippe Coutinho and Julio Cesar are back from injury.
Dejan Stankovic, Ivan Cordoba and Cristian Chivu are suspended, while Wesley Sneijder, Walter Samuel and MacDonald Mariga are sidelined.
Sulley Ali Muntari is not included, as he is currently in the process of completing a transfer to Sunderland.
Inter squad: Julio Cesar, Castellazzi, Orlandoni; Zanetti, Lucio, Maicon, Ranocchia, Materazzi, Benedetti, Santon, Natalino; Thiago Motta, Kharja, Cambiasso, Obi, Coutinho; Pazzini, Eto'o, Milito, Pandev
