Newcastle United midfielder Haris Vuckic has been warned off signing for Rangers.
After an impressive loan with Gers, Vuckic's future remains in the air but he still has one year left on his contract at the Magpies.
Slovenia boss Srecko Katanec said: "Haris played for Rangers in the second division in Scotland.
"I was disappointed, not just with him, but with the quality of the league he was playing in.
"I would have thought Rangers would have had a better team."
