England-Panama (Group G). If England wins, which is very likely, they and Belgium will be through to the next round, Panama and Tunisia will be out. My pre-tourney prediction has England winning, 3-1, with 2 goals by Harry Kane and one by Danny Welbeck, with Luis Tejada scoring the consolation for Panama. The possible absence of Dele Alli could be a problem for England, but not enough for them to lose.
Japan-Senegal (Group H). Both winners in their first match, and if there's a winner in this one, that team could guarantee a spot in the knockouts. I predicted that Sadio Mané would score two in leading Senegal to a 2-1 victory, Japanese goal for Shinji Okazaki. But Japan is fully capable of a win. I am not the person to rely on with this group ... I predicted Poland and Colombia would advance, and they both lost their opening match.
Poland-Colombia (Group H). The loser of this match, if there is one, is likely to be eliminated, although a draw would keep both team's hopes alive. I predicted a 1-1 draw, goals by Robert Lewandowski and Radamel Falcao, but that's when I thought these two would advance. Colombia could squeak out a win, especially if Lewandowski doesn't improve on his performance against Senegal.
