Are two teams from the same league who are also friends allowed to be in the cup final against each other. I ask because my team has made the final but my friend's team has just lost both legs of their semi final against a much inferior team from a lower level.

I understand the unpredictable nature of football and that this is factored in but this result was ludicrous. I can only assume that this was preordained to stop us playing each other in the final.
