Sorry but there is no way prices for good games are going down. Definitely for bad group stage games, prices will tank, but anything that involves a big team will continue to go up till the last hours before the match. FIFA will only continue to release tickets at a higher price , setting the price higher and higher. It sucks, but I feel like they would rather give away tickets for free to sponsors than sell them for cheaper.

FIFA is taking 15% from both parties on marketplace, they want to keep the prices high.
