The Guardian’s Knowledge column examines footballers with unusually high numbers of club appearances, naming Uruguay’s Sebastián Abreu as Guinness World Records’ official holder for the most professional clubs. Abreu represented 31 sides during a 26-year playing career, while English forward Jefferson Louis is cited as an unofficial leader after playing for 51 clubs over 28 years.

The article also explores players whose names contain the letters of the clubs they represented, using rules that exclude generic suffixes such as “United” or “City” and prevent letters being reused. Examples include Paolo Maldini and Milan, Lucas Radebe and Leeds, and Neymar da Silva Santos Júnior and Santos; it notes Derek Asamoah, aged 45, has joined his 19th club, Whitstable Town.
