A draw with Panama guarantees us top 4. No matter what - unless goal differential does not matter.
We'd have 23, they'd have 20. Even if they win they're last match - we currently are +9 goal differential, they are +1, Costa Rica is +2. We'd have to get blased against Costa Rica and they'd have to score a crazy amount, basically 5-0 vs both Us and Honduras to have better goal differential.
Obviously Costa Rica winning both remaining matches pushes us to 4th place but we are in some sort of qualifying based on points and goal differential. We have 6 wins, a draw versus us the and the maximum that Panama can get to would be 6 wins... and again, we have goal differential on our side.
They'd have 19. It wouldn't even come to tie breakers.
