The fact that the Serie A champions had not lost a group game at home since December 2009 speaks volumes about the magnitude of the Red Devils' achievement. I hope we arrive on time!
But they fell apart in the last five minutes as Jose Mourinho's side came from a goal down to claim a famous victory. "I probably shouldn't have done it, and with a cool head I wouldn't have done it, but with my family insulted, including my Inter family, I reacted like this", Mourinho said.
Even if they had nicked a draw, I would have been delighted. The club's greatest ever performance saw them come from 2-0 down there to triumph and reach the Uefa Champions League final in 1999. United were more organised in the first half than they were at Bournemouth - it would have been hard to be that bad again - and the United manager got his substitutions right, particularly bringing on Marouane Fellaini who caused a lot of problems in the last 10 minutes.
Meanwhile, United secured three vital Champions League points.
"Speaking to BT Sport after Wednesday's win, Ferdinand said: "[The win was] exactly what we wanted, going into the derby at the weekend as well, what a fantastic result.
Undeterred by Ronaldo's abdominal muscles, United battled on, and got their break four minutes from time, when substitute Juan Mata curled home a sublime equalizer from a set piece just outside the area. He really should have approached the game determined to show his old fans what they were missing, but he was simply swallowed up Juve's midfield of Miralem Pjanic, Sami Khedira and Rodrigo Bentancur. He still has the odd mistake in him, although that side of his game is improving, but he reads situations well and is a lot quicker than most people think.
This time he had another win to celebrate, after watching his team fight back from Cristiano Ronaldo's spectacular opening goal.
If you keep beating teams like that - from behind and without playing especially well - then that starts to build belief.
It was the eighth goal this season for the 33-year-old Ronaldo who arrived from Real Madrid in July in a deal estimated to cost 340 million euros in total over four years, on top of the 110 million-euro transfer fee.
The familiar swagger and glint in the eye, that have been missing for so much of his turbulent Manchester United tenure, have all returned.
The celebration unfrotunately did not match up to the goal; after netting the opener, 5-time Ballon d'Or victor Ronaldo then wheeled away to celebrate simply by lifting up his shirt to reveal his chiselled six-pack to the crowd.
