I haven't given up :-)
Let's say, conservatively, that Italy beat Costa Rica and Uruguay by 1-0 each and it is in their interest to finish top of the group. That would leave Uruguay at a -2 goal difference, putting them back on the same level as England. Costa Rica would still have a +1 goal difference.
But for every goal England then scores in England v Costa Rica, the English side's goal difference goes up while Costa Rica's goes down. If England beats Costa Rica by 2-0, that would put Costa Rica on a -1 goal difference — and England on a big fat zero and 3 teams with 3 points!!!
That would be good enough for England to squeak through to the next round in second place. (It doesn't matter how much Italy beat Uruguay by — just that they beat them).
So come on Super Mario - give it your best :-)
