The Russian side now sit on six points, with a win putting them equal to Liverpool - and their 1-1 draw with the Reds earlier in the competition would be enough to see them through.
Liverpool have been installed as the hot 2/9 favourites for the three points, with Spartak out at 12/1, while a draw is available at 13/2.
The alleged incident happened during Liverpool's UEFA Youth League match with the Russian side at Prenton Park on Wednesday afternoon.
