The average cost for a single collector to complete Panini's World Cup 2018 sticker book is £773.60 (€882.52), a leading mathematician has calculated.
Professor Paul Harper has considered the best case scenario and the most likely cost of filling this year's album after the Italian brand announced the cost of a pack of five stickers was increasing from 50p to 80p.
With 32 squads of players, as well as special stickers for managers, stadiums and World Cup legends, the task of completing the album is a considerable one.
