"Got, got, need" is echoing around school grounds and offices as Euro 2016 edges closer - and perhaps manufacturer Panini 'need' to brush up on their research.
This summer's album features stickers of 480 players spread across the 24 teams in France, although some 17% of those featured will not be playing at this summer's tournament.
In total, 82 players with profile stickers are not in the 23-man squads days out from the Euros, with Wales and Austria the only nations without one erroneous inclusion.
Germany, Russia, Spain and England have six wrong players apiece, with Phil Jones, Luke Shaw, Leighton Baines, Alex Oxlade-Chamberlain, Theo Walcott and Danny Welbeck in the Three Lions' 20-strong group of stickers.
Given 18-year-old star Marcus Rashford had not even made his Manchester United debut until a month after Panini sticker album was signed off, perhaps it is not a surprise!
