ROME - Brief news ahead of this weekend's matches in Serie A: New signing Diego is confident of making an impressive Serie A debut in Juventus' league opener against Chievo Verona in Turin on Sunday despite not being his best after a thigh muscle problem. The injury caused the Brazilian playmaker to miss most of the pre-season but he came back on Monday with a fine showing and a goal in a friendly against AC Milan. "I'm not yet 100 percent. I'll be better for my league debut on Sunday," the former Werder Bremen player told reporters. Felipe Melo, another Brazilian newcomer, is suspended, while fellow midfielders Sebastian Giovinco and Mohamed Sissoko are injured and captain Alessandro Del Piero is a doubt because of a back problem. Former Barcelona forward Samuel Eto'o should make his Serie A debut for champions Inter Milan at the San Siro against promoted Bari on Sunday alongside Argentine signing Diego Milito. With the club in talks to buy Dutchman Wesley Sneijder from Real Madrid, Jose Mourinho will probably use Dejan Stankovic as his advanced midfield playmaker this weekend. Patrick Vieira, who had been strongly linked to a move away from Inter in the close season, is tipped to get the holding role in front of the defence with Argentine Esteban Cambiasso likely to be sidelined until early October after minor knee surgery. Serie B champions Bari, whose owners reached a preliminary agreement to sell the club to an American real estate businessman this week, signed Argentine midfielder Sergio Almiron on loan from Juventus on Thursday. Klaas-Jan Huntelaar will not be able to make his league debut for Milan at Siena on Saturday because he is banned after being sent off in his last Liga game at former club Real Madrid. With the Netherlands international unavailable, new coach Leonardo is likely to field Alexandre Pato and Filippo Inzaghi up front, with Ronaldinho in the hole behind them. Attacking midfielder Davide Di Gennaro, a Milan academy product who spend last season on loan at Reggina, is expected to be out for two months after the club said he had foot surgery on Thursday. Forward Emanuele Calaio is suspended for Siena.
