Here’s an interesting conundrum for you all to consider
If England and Belgium win their next games and so both qualify before the final game, which merely becomes a question of who tops the group. Brazil and Germany improve on initial matches and qualify, but the latter is second to Mexico and so play Brazil in the last 16. This is known before the Eng-Bel match, whilst the winners of Group H (Japan, Poland, Senegal, Columbia) isn’t known but isn’t exactly terrifying.
Now then the winners of Eng-Bel, if they win their R2 match, will face Germany or Brazil. The losers, again if they win in R2, would face someone like Mexico or Switzerland.
