The easiest way for Costa Rica to advance to the round of 16 is to beat Italy today.
But, that may not be so easy.
Here are a few scenarios of today’s outcome:
1. Costa Rica beats Italy: Costa Rica advances
2. Costa Rica ties Italy: it needs to tie or win England to advance
3. Costa Rica loses to Italy and England: Costa Rica could still advance, but needs Italy to beat Uruguay.
Again, beating the Italians today is really the only way to assure itself a spot in the round of 16.
