The oracle cat will make the prediction in the Hermitage by selecting a plate with food marked with the national flag of either France or Belgium.

The game will take place at the 64,500-seater St. Petersburg Stadium on Wednesday morning (AEST).

Achilles, who also predicted the match winners during the 2017 Confederations Cup, has already made six predictions for the World Cup games.

He correctly predicted Russia's wins over Saudi Arabia and Egypt, Iran's victory over Morocco and Brazil's defeat at the hands of Costa Rica.

He has made only two mistakes so far when he chose Nigeria as the winner of the match against Argentina and when he chose Switzerland as the winner of the Sweden match.

Earlier it was reported that Achilles had been chosen as the World Cup animal oracle for being the most stress-resistant and human-oriented of about 50 cats living at the Hermitage.

Russia is hosting its first-ever FIFA World Cup, with the final set to be played at Moscow's Luzhniki Stadium on Sunday.
