The game on Saturday was an incredible let down. Referees wrongly ruled 2 early goals by Juárez offsides and then missed a rather clear offsides call on Necaxa's second goal. To make matters worse they called a foul every time a Necaxa player went to ground and allowed them to milk the clock with their theatrical performances following the so called "fouls."
Necaxa isn't moving to el DF anytime soon. The have a brand new 25,000 seat stadium (Estadio Victoria) in Aguascalientes and they have been easily filling it with fans. It'll be tough to find an empty seat now that the team is back in the first division.
I don't really know much about the current situation of Atlante in Cancun. However, I do know that they brought more away fans to Juárez for the final than Necaxa did. Their fans had to travel a much larger distance to do so as well. If that's any indication of their situation they're fine and well in Cancun.
