Antony had looked a promising player during his two full seasons at Ajax and several top European teams had expressed an interest in signing the winger. However, United's decision to pay £82 million ($102m) was staggering, even at the time.
Still, the presumption was that he would flourish in Manchester under his former boss in Amsterdam, Erik ten Haag, who had just taken over at Old Trafford, and in fairness to Antony, there were some flashes of quality during his first season in the Premier League.
However, by the midpoint of his second, it was clear that Antony could do a couple of flicks and tricks - but little else. His performances became increasingly farcical and were used as a stick with which to beat Ten Hag.
It, thus, came as no surprise to see Antony leave United shortly after the Dutchman's dismissal. The problem for United, though, is that they've yet to make any money back on the Brazil international, as they're still paying a significant chunk of wages while he spends the rest of the 2024-25 campaign on loan to Real Betis, who are under no obligation to buy either.
Furthermore, the acquisition of Antony is being held up as the ultimate example of why United are currently in danger of falling foul of the Premier League's Profit & Sustainability Rules (PSR). As this list underlines, they've made a succession of shocking signings over the past decade - and Antony is the worst of a very bad bunch.
