The players who had appeared for a remarkable number of clubs by their 23rd birthday.

Former Aston Villa striker Jhon Duran, 22, has joined Benfica on a season-long loan - the seventh club he's played for Some of football's most celebrated players stayed loyal to a single club for their entire career. The Premier League's most-decorated player, Ryan Giggs, is one, so too AC Milan legend Paolo Maldini, Roma's Francesco Totti and Arsenal defender Tony Adams. Perhaps some current players such as Bukayo Saka and Phil Foden might join them too. But there are players at the other end of the spectrum, those who can look back on a lengthy list of employers, and sometimes while their career is still in its infancy. The most famous current example is Jhon Duran, the former Aston Villa striker joining the seventh club of his career at the age of just 22 last week. He joins others who were in danger of acquiring the journeyman tag before their 23rd birthday. These are some of those players. Former USA international Freddy Adu played for 15 clubs during his career - more than half of which were by the age of 22.
