Prime
The 1999 treble or the 2008 Moscow winners with peak Ronaldo. Two different United sides, both legendary.
Editorial verdict
The 1998/99 treble is United's defining achievement; the 2007/08 side is our pick for playing strength. Peak Ronaldo, Rooney and Tevez attacked ahead of Ferdinand and Vidić, giving Ferguson elite quality in every line.
Candidate 1
