Why have Manchester United only had two truly successful managers?

Manchester United's struggles to find a successful successor to Sir Alex Ferguson have raised questions about the club's leadership, identity and long-term direction.

A Sky Sports analysis explores why only three managers have ever led United to English league titles: Ernest Mangnall, Sir Matt Busby and Ferguson. While Mangnall's achievements have largely faded from public memory, Busby and Ferguson won 18 of the club's 20 league championships between them.

Their influence extended far beyond trophies. Both built successful teams and helped establish the standards and identity associated with Manchester United.

Since Ferguson retired in 2013, the club have appointed a succession of permanent and interim managers, including David Moyes, Louis van Gaal, Jose Mourinho, Ole Gunnar Solskjaer and Erik ten Hag. Several won silverware, but none managed to restore sustained league dominance.

The analysis suggests the problem cannot be blamed on managers alone. Changes in ownership, recruitment failures, a lack of clear leadership and the departure of key figures alongside Ferguson all contributed to the decline.

Former interim boss Ralf Rangnick also identified a leadership problem, questioning who was making important decisions at the club.

The central argument is that United need more than another high-profile appointment. They must build a coherent football structure capable of delivering success without relying on one legendary manager.
