The former Arsenal player’s legal action against Fifa’s ‘draconian’ rules could lead to the age of Bosman 2.0

By the time Lassana Diarra played his last game as a professional footballer, on 20 October 2018, he had become a “what if?” player. What if he had stayed more than a single season at Arsenal? What if he hadn’t made the catastrophic decision to leave Real Madrid and La Liga for Anzhi Makhachkala and the Russian league? What if he hadn’t made the even more disastrous move from Anzhi to Lokomotiv Moscow? What if he hadn’t had to pull out of Didier Deschamps’s Euro 2016 squad at the very last moment because of a knee problem?

Another injury forced his retirement shortly after a rare cameo for his last club, Paris Saint-Germain, for whom he was no more than a squad player. Diarra was set to remain a footnote in the history of some prestigious clubs, a series of unanswered questions, something of an enigma – but then we have a legal case, which will finally be settled on 4 October, putting the final full stop to a story that has been dragging on for a decade. It is Diarra v Fifa and if the player wins it could completely change the transfer market, possibly leading to anarchy.
