Queens Park Rangers have lost out on Porto centre-back Rolando, who has now signed for Serie A side Napoli.
Partenopei have also confirmed the capture of 18-year-old Croatian Josip Radosevic from Hajduk Split.
Rolando had been continually linked with a move to Loftus Road, but Hoops boss Harry Redknapp seemingly gave up the chase after landing Anzhi Makhachkala's Christopher Samba.
Meanwhile, highly-rated Radosevic was wanted by a number of clubs in Italy, including Inter Milan.
However, the Coppa Italia champions have beaten off the competition to secure his signature.
