Sir Alex Ferguson's Greatest Trophy Triumphs in Club Football

Manchester United clinched the Premier League trophy on Monday night with a 3-0 win over Aston Villa at Old Trafford.

The title brings the club's tally up to a remarkable 20 league championships, while Sir Alex Ferguson has now claimed 49 cups in his managerial career with United and Aberdeen.

The 71-year-old has been at Old Trafford since 1986 following a period of sustained success at Pittodrie.

But what have been the biggest cup victories in Ferguson's managerial career to date?

Read on to find out more.

Scottish Premier Division, 1979-80

Ferguson became Aberdeen manager in 1978 after spells in charge of East Stirlingshire and St Mirren, replacing Celtic-bound Billy McNeill.

In his first season at Pittodrie, the Dons reached the semifinals of the League Cup and the Scottish Cup and finished fourth in the Scottish Premier League table.

But Ferguson introduced a siege mentality at the club to offset the duopoly created by Glasgow giants Celtic and Rangers over the years.

The move paid dividends when Aberdeen lifted the Scottish Premier Division title in 1980 to become the first team outside of the Old Firm to win the league in 15 years.

This was only the second time the Dons had won the title since their first championship in 1955. Ferguson would go on to win the title in 1984 and 1985 with the Pittodrie team.

European Cup Winners' Cup, 1983

In 1983, Ferguson stamped his mark on European competition by guiding Aberdeen to a stunning victory over Real Madrid in the European Cup Winners' Cup final in Gothenburg.

The Dons had seen off FC Sion, Dinamo Tirana and Lech Poznan before completing a 3-2 aggregate victory over German giants Bayern Munich in the quarterfinals.

Aberdeen defeated now-defunct Belgian side Waterschei 5-1 in the first leg of the semifinal to make comfortable progress to the final.

The 2-1 win over Real Madrid, where goals from Eric Black and John Hewitt overcame the Spanish giants who were managed by Alfredo di Stefano, remains a long-lasting memory for many Aberdeen fans (BBC Sport).

It was a quite magnificent achievement and placed Aberdeen on the football map as only the third Scottish team to win a European trophy. They remain the last one to do so, also.

FA Cup, 1990

Ferguson succeeded the sacked Ron Atkinson at Manchester United in November 1986, but even the Scot struggled to knock Liverpool off their perch as the best team in England at the time.

Everton were also a force at the time, making Merseyside the heartbeat of the game in England.

United finished second behind Liverpool in the First Division in 1988 but drifted off the pace the following season, ending up in 11th.

High-profile purchases such as Neil Webb, Mike Phelan, Gary Pallister and Danny Wallace at the start of the 1989-90 season offered promise, but the team struggled and the nadir came with a 5-1 defeat at Manchester City.

United went on a run of six defeats and two draws before being paired with Nottingham Forest in the FA Cup third round in January 1990. Mark Robins scored the only goal of the game to give Ferguson and United some hope of silverware.

United, who finished 13th in the league in 1990, reached the FA Cup Final but could not see off Crystal Palace, and the match ended in a 3-3 draw with Old Trafford goalkeeper Jim Leighton blamed for costly errors.

Ferguson dropped Leighton for the replay and replaced him with Les Sealey, and Lee Martin scored the only goal of the game to win the cup for United and his manager.

Premier League, 1992-93

Ferguson and United missed out on the final First Division title to Leeds United on the last day of the 1991-92 season, but there was to be no disappointment the following year.

The United manager made only one major signing in the summer of 1992 with Dion Dublin arriving from Cambridge United, and the team got off to a sluggish start. United were 10th in the table in November after the new forward had broken his leg early in the campaign.

However, Ferguson raided Elland Road for the mercurial talents of Eric Cantona (this was the time before the transfer window), and the Frenchman developed a potent partnership with Mark Hughes.

United claimed their first league title for 26 years when nearest challengers Aston Villa lost to Oldham Athletic, and Ferguson's team enjoyed a party atmosphere at Old Trafford in their subsequent match against Blackburn Rovers.

Champions League, 1999

Few people will need reminding of the events at Camp Nou in May 1999, where United slugged it out with Bayern Munich for the Champions League trophy.

But, for the uninitiated, Mario Basler's early free-kick was cancelled out by United substitute Teddy Sheringham in the 90th minute of the final.

Another United sub, Ole Gunnar Solskjaer, hit the winner moments later after Sheringham had nodded David Beckham's corner into his path.

This was the pinnacle of Ferguson's time at Old Trafford to date. The Scot had guided the team to the 1991 European Cup Winners' Cup with a win over Barcelona, but Ferguson had been eyeing UEFA's elite tournament since its inception.

Now he was able to celebrate breaking another glass ceiling in his pursuit of greatness with the Old Trafford side by claiming a remarkable treble of Champions League, Premier League and FA Cup in the 1998-99 season.

Premier League, 2010-11

Ferguson had claimed his greatest challenge was to "knock Liverpool off their perch" (The Guardian). On May 14, 2011, he finally did it. In domestic competition, at least.

United needed just a point from their trip to Blackburn Rovers to secure the Premier League title ahead of Chelsea.

Brett Emerton had given relegation-threatened Rovers a first-half lead, but Wayne Rooney scored from the penalty spot after Blackburn goalkeeper Paul Robinson was adjudged to have brought down Javier Hernandez in the 73rd minute.

The solitary point was enough for Ferguson to move United ahead of Liverpool in the record number of title victories with his team's 19th championship triumph.
