Wolves boss Mick McCarthy says Nenad Milijas will be a great success at Molineux.
"He'll certainly bring quality to us," he said. "He's 6ft 1in tall, left-footed that will give us plenty of balance. He's a very comfortable player and he plays in different positions.
"He 'sits' for the national side and he played in behind the front two when I saw him play for Red Star and I've seen on a number of DVDs he's a quality player.
"He can slot people in, he scores goals and he's an all- round top midfield player."
