FC Internazionale Milano have secured the signings of midfielders Zdravko Kuzmanović and Mateo Kovačić, winger Ezequiel Schelotto and goalkeeper Juan Pablo Carrizo.

Serbian international Kuzmanović joins from VfB Stuttgart for a reported fee of €2m, signing a contract which ties him to Inter until 2017. The 25-year-old former FC Basel 1893 midfielder returns to Serie A having scored three goals in 70 Serie A games for ACF Fiorentina between 2007 and 2009. "I'm glad to be joining a great side like Inter," he said. "I look forward to meeting my new team-mates."

Kovačić, 18, arrives from GNK Dinamo Zagreb for a fee that could reportedly rise to €15m. He appeared in all six of Dinamo's UEFA Champions League group stage games this season. The Croatian Under-21 international has penned a contract until 2017 with the Nerazzurri. "It's a dream for me," he said. "I will do everything to make our fans happy."

Schelotto, meanwhile, comes in from Atalanta BC for around €3.5m plus Marko Livaja, scorer of four UEFA Europa League goals this term. Inter, however, have retained 50% of the Croatian striker's playing licence. Schelotto, a 23-year-old right winger, formerly at AC Cesena and Calcio Catania, made his Azzurri debut in August, figuring as a substitute in a 2-1 friendly defeat of England.

Inter have also recruited goalkeeper Carrizo from S.S. Lazio on a two-year deal. The 28-year-old will deputise for Samir Handanovič after Luca Castellazzi suffered a shoulder injury.
