In recent discussions regarding the interpretation of rules surrounding corner kicks, DFB rule expert Marco Fritz highlights the increasing trend of blocking tactics employed by teams, which have proven quite effective in scoring goals. This has led to a surge in complaints over how officials assess fouls during aerial duels between goalkeepers and field players, particularly emphasizing notable instances, such as the Borussia Dortmund's two goals during their 4-0 victory against Mainz, which were influenced by these tactics.

Fritz notes that while teams adapt and innovate strategies to exploit existing uncertainties in the rules, it raises questions about the clarity and consistency of officiating, especially in light of the recent debates around handball rules. As teams become more strategic in exploiting these ambiguities—evidenced in recent matches—it suggests a shift in how the game is played and how referees will need to respond to these evolving tactics while maintaining the integrity of the sport.

Going forward, coaches will need to find effective solutions to navigate the fine line between competitive tactics and fair play, ensuring their strategies do not cross into foul territory. The potential for more disputes over foul calls, coupled with demanding adherence to newer interpretations of the rules, presents a significant challenge for both teams and officials in maintaining the framework of the game.
