Manchester United 1998-99: The best wins of Ferguson's treble from Turin to Barcelona | OneFootball

Undimmed by the passage of time and present-day struggles at Old Trafford, Manchester United's 1999 treble remains the greatest single-season achievement in English club football history.

While Manchester City's current domestic dominance is one of towering points totals and smashed records, Alex Ferguson's finest hour was one built upon a death-or-glory knife edge.

From Birmingham to Barcelona via Turin, a United side packed with household names secured their legacy in unforgettable style.

To mark the 20th anniversary of a remarkable triumph, we look back at some of the signature wins in a campaign that came to define Ferguson's Old Trafford dynasty.

Manchester United 2 Liverpool 0 (Premier League, September 24)

Never mind three trophies, United were yet to claim three league wins by the time bitter rivals Liverpool arrived at Old Trafford in late September and Ferguson's men had been beaten 3-0 by reigning champions Arsenal four days earlier. Denis Irwin hammered in a 19th-minute penalty after fellow Republic of Ireland international Jason McAteer was penalised for handball and Paul Scholes thrashed left-footed into the top corner 11 minutes from time to crown a trademark counter-attack. The victory launched a three-match winning streak – United were up and running.

Manchester United 2 Liverpool 1 (FA Cup fourth round, January 24)

Tottenham knocked a much-changed United out of the League Cup in December and Liverpool looked set to end their FA Cup ambitions after Michael Owen nodded in an early opener. Dwight Yorke converted Andy Cole's knockdown from a floated David Beckham free-kick to level in the 88th minute and, following some neat footwork from Scholes, Ole Gunnar Solskjaer pounced in stoppage-time – a theme we'll return to later.

Nottingham Forest 1 Manchester United 8 (Premier League, February 6)

Forest's day did not look like it could get much worse when Solskjaer trotted on to replace Yorke in the 71st minute, United already 4-1 to the good at the City Ground. The "Baby-Faced Assassin" duly pilfered four goals in the final 10 minutes of the contest as United clinically and mercilessly pulled their ill-equipped foes to pieces.
