Zlatan Ibrahimovic, who last year - at the age of 35 - led his rag-tag Manchester United team to three trophies, after swapping an ostensibly cushy role at PSG to try his hand in what many consider to be the world's toughest football league, is very much the exception that proves the rule.
Among mortals, football careers are generally short. In fact, you can probably be only sure of getting about fifteen seasons before your legs begin to abandon you. After that, you can promptly kiss goodbye to the 50-match season you used to enjoy, and start preparing for life on the sidelines, where even the mere sight of you beginning to warm up elicits a chorus of muted sighs from the terraces.
And careers, so often led by the arbitrary whims of luck and circumstance, can sometimes deteriorate much sooner than that. Off-field issues, ill-timed injuries, and even physical or mental exhaustion have brought down some of the very best players (or at least drastically affected their ability to perform at the top level).
The game, as they say, is a cruel mistress.
