Konrad Plautz of Austria may be appointed Loko-CSKA clash referee.
The Austrian referee has already been to Russia as he worked at Zenit-Krylya Sovetov clash the previous season.
"Nikolay Levnikov called me up and suggested I should referee the clash," said Konrad Plautz to Sport Express.
"He also added that an official offer would follow soon."
"I must admit I liked it to referee Premier Liga clashes so I would be glad to come to Russia again."
