The soccer card/sticker market has been popular around the world for decades, but it’s only been since the early 2020s that the category has been able to capture American collectors’ attention. But now that it has it, they can’t kick their habit.From retired legends (Pelé, Diego Maradona) and modern icons (Lionel Messi, Cristiano Ronaldo) to budding stars (Erling Haaland, Christian Pulisic), whatever product companies like Panini and Topps release, there’s usually a frenzy from the futbol faithful.
