It's unusual these days - but there are still a few one-club men left in the game. 33 to be precise, from the last 31 years in Europe's top five leagues.
That's of clubs currently in the top flight of England, France, Germany, Italy and Spain. And we've taken players who made their debut in 1990 or after. That excludes some legends, unfortunately; Paolo Maldini, for one, who spent his entire career at AC Milan. Tony Adams, who captained Arsenal across three decades.
Many of us thought that Lionel Messi would become another of these gents. Xavi and Andres Iniesta retired out to Qatar and Japan respectively, while arch-nemesis Cristiano Ronaldo is now on his fourth club. But there seemed to be a certain romance between Barcelona and Leo.
Well, that love affair ended in tears, the GOAT bidding Barca farewell in an emotional press conference. He's a PSG player now. But these chaps? There's only one club for them.
