Russia has shown they have the potential to beat Croatia and make it through to the semi-finals, former Dynamo Moscow and Germany striker Kevin Kuranyi said on Wednesday.

The 36-year-old retired striker took part in a friendly match between Russia's and Germany's supporters at Red Square in Moscow on Wednesday.

"I lived in Moscow for five years and I'm glad to come back here. I like this city and its residents. A lot of people come here now, during the World Cup. They are also happy to be here and see the beauty of Moscow," Kuranyi added.

Russia will face Croatia in their last eight clash at Sochi's Fisht Stadium on Saturday.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the matches being played in 11 cities across Russia.
