I do not remeber any game in Russia which finished by less than 20-21 shots so far. This one depsite of level of soccer and ranking has potential to take easly 22 and more. Icleand average 10-11 while Nigeria even more.
Opta says that Nigeria take average 14 per game, while Iceland only 8 but rely on previous encoutner over Argentina Iceland is eager to suprise again, and again. Nobody gave them any chance to repeat success from past tournament but here again, your welcome.
