This is a complicated group so here it is.
Russia (4) -- need a draw to advance, a win to win group. Wuld win the group likely on gd with a loss and czech draw. Only chance of being sent home is a loss and a non draw in the other match.
Czech (3) -- need a win to advance for sure, a draw gets them thru if russia doesnt lose (wuld likely b eliminated witha draw if russia lost on gd). A loss they r out.
Poland (2) -- simple win or go home. If greeks get a shock win and they win they take the group, if greeks draw and they win then they will likely finish 2nd on gd.
Greece (1) -- win and or go home. Surprisingly they dont need any help. A draw in the other gamd wuld put them thru on gd, if other game is not a draw they beat russia on h2h.
Probably the most exciting final group day we will see. No one has actually advanced yet somehow from any group and the only teams finished r sweden and ireland.
