Bologna have bolstered their midfield with the signing of Uruguayan international Diego Perez and the arrival of Serbian Ivan Radovanovic on loan.
Perez who has signed a four-year deal, arrives from Monaco where he has played for the past six seasons.
The 30-year-old was one of Uruguay's standout players at the 2010 FIFA World Cup where they reached the semi-finals.
He joins several compatriots at Bologna including defender Miguel Britos and midfielders Henry Gimenez and Gaston Ramirez.
Meanwhile, Serie B club Atalanta have loaned out Radovanovic for a year with an option to buy.
Bologna, without a coach, opened their Serie A campaign with a solid 0-0 draw with champions Inter on Monday.
