#9 Peter Schmeichel
"The Great Dane" is probably one of the greatest goalkeepers of all time, let alone of Manchester United.
United have been blessed with some pretty incredible goalkeepers in the Premier League era, but it is a testament to Schmeichel's incredible abilities that he's considered the uncontested number 1 ahead of van der Saar and de Gea.
When Sir Alex signed him from Brøndby in 1991 for £505,000, he described it as "bargain of the century", and he wasn't very far off. Good goalkeepers are worth a dime a dozen these days, and Schmeichel is much better than just "good".
In the 92/93 season, he kept 22 clean sheets en route to United's first league title for 26 years.
For eight seasons between 1991 and 1999, he made 398 appearances for United in all competitions, winning 5 Premier League titles and the Champions League in 1999, which was part of the treble that made United the first English club to achieve that particular milestone.
In 1992, he helped Denmark forge one of the biggest underdog stories in football, as they won Euros after having entered the tournament only because of Yugoslavia's civil war.
In the year 2001, Schmeichel was voted the best goalkeeper of all time in a poll conducted by Reuters, ahead of the likes of Gordon Banks and Lev Yashin.
