Ruben Amorim leaves Manchester United as their Worst Manager - Here's How Three Stats Prove It!

In a move that surprised few but disappointed many, Manchester United parted ways with Ruben Amorim on January 4, 2026, after a tenure marked by dismal performances and mounting frustration.

Hailed as a tactical innovator when he arrived from Sporting CP in November 2024, Amorim was expected to revive the Red Devils' fortunes following Erik ten Hag's sacking. Instead, his time at Old Trafford has etched his name into the club's history books for all the wrong reasons.

Worst Win Ratio (32%)

Amorim's 32% win rate in the Premier League is not just poor, it's historically abysmal for a club of United's stature.

• Sir Alex Ferguson: 65.2% over 810 games.
• Jose Mourinho: 53.8% over 93 games.
• Erik ten Hag: 51.8% over 85 games.
• Ole Gunnar Solskjær: 51.4% over 109 games.
• Louis van Gaal: 51.3% over 76 games.

Even David Moyes, often cited as one of United's biggest flops, managed 50% in his brief 34-game stint. Amorim's points per game averaged around 1.2-1.3 in the league,

a figure that would have seen United battling relegation in a full season-far from the top-four aspirations that defined his mandate. His teams lost 15 of 29 early league games, a faster rate of defeats than Ten Hag's initial struggles.

Highest Goals Conceded Per Game (1.53)

Defensive frailty was a hallmark of Amorim's United. Conceding 1.53 goals per game in the Premier League, his side leaked goals at a rate unmatched by any previous manager. This included vulnerability from set pieces, where they conceded more than any other United boss in the era. Over 42 league matches, United shipped 64 goals while scoring only 58, resulting in a negative goal differential of -6.

Comparisons highlight the regression:

• Ferguson: ~0.87 goals conceded per game (703 in 810).
• Mourinho: ~0.92 (86 in 93).

Under Amorim, only relegated sides and bottom-table teams conceded more during his tenure, with United ranking sixth-worst in the league for goals against.

Lowest Clean Sheet Ratio (15%)

Perhaps the most glaring indictment was United's inability to keep clean sheets, managing just 15% in the Premier League-the worst ratio ever for a United manager. Across 63 games in all competitions, they achieved only 9 shutouts, a staggering 14.29% rate. In the league, it was even lower at times, with just four clean sheets in 25 games early on.

This defensive sieve contrasted sharply with the club's history. For instance, under Mourinho and Van Gaal-known for pragmatic defenses, clean sheet rates were significantly higher, often around 30-40% in their peaks. Amorim's teams were among the lowest in the entire Premier League for clean sheets during his spell, underscoring a systemic breakdown.

Beyond the core stats, Amorim's United struggled offensively too. They scored just 1.2 goals per game in his 15 initial league matches, with accuracy issues plaguing their shots (only 59 of 190 on target). Only a handful of bottom-table teams scored fewer goals during his reign. United finished 15th in the table at one point, closer to relegation than Champions League spots.

Fan discontent grew, with sections of supporters calling for his head as early as mid-2025. Comparisons to Mikel Arteta's Arsenal turnaround fell flat-Arteta won 54% of his first 50 games compared to Amorim's 38%. Ultimately, a string of humiliating defeats and lack of results sealed his fate.
