Former Slovenia star Zlatko Zahovic has slammed David Alaba as "disrespectful" for not knowing Jan Oblak and Josip Ilicic's names.
"Their goalie is pretty good, and they have one [a good player] on the right of the attack," the 26-year-old said.
Alaba has faced Oblak four times in the Champions League and the goalkeeper has established himself as one of Europe's best in his position after five years with Atletico Madrid.
Meanwhile, 31-year-old Ilicic has represented Palermo, Fiorentina and Atalanta and has 58 caps for Slovenia to his name.
Zahovic told Ekipa: "It is disrespectful not to know one of the best goalkeepers in the world and a player like Josip Ilicic - that does not show a mark of respect."
Meanwhile, Slovenia boss Matjaz Kek praised Alaba's talent as a player but was as surprised as Zahovic by the eight-time Bundesliga winner's attitude.
"I know everything about Austria, Jan Oblak is no stranger," he said. "Everyone respects their opponents in their own way. Alaba is a great player, his career is impressive."
Austria's next Euro 2020 qualifying game comes against North Macedonia on June 10, while Slovenia take on Latvia.
Poland are top of the group on nine points from three games, with Israel two behind.
North Macedonia sit third in the group, with Austria and Slovenia closely behind, while Latvia sit bottom with zero points.
