Are all of the cup games included in a season ticket? If so, that is a fantastic deal compared to American sports. NFL ticket prices are far, far more expensive on average and don't even include the cost of tickets to the playoff game(s), should the team qualify. A number of professional franchises are also now requiring fans to purchase "personal seat licenses," so then fans can pay for the opportunity to pay for their season tickets. NBA and MLB tickets can also be absurdly expensive but are perhaps a better deal since you have the opportunity to see 41 and 81 games, respectively.
I pay ~$1500 for two season (19 home games) tickets to watch my university basketball team and I don't even sit in the lowest section. Bigger, more prestigious schools that play in newer arenas charge even more. And that's at the collegiate level.
We love our sports in America. Almost as much as we love our billionaires and corporations. Team owners often extort the public to pay for brand new stadiums, often when the one they currently play in isn't even 25 years old. If they don't get what they want they pack up and leave.
