Beckham Snr will be at Man Utd to see David play
But it was always the thought of a return for the ex-England captain to the ground where he forged his name which has been simmering ever since the draw was made before Christmas.
Ted, a life-long United fan, admitted to the Sunday Express: "I was excited when the draw was made. I texted David straight away. He was gobsmacked. We both were because we couldn't wait to be involved at Old Trafford.
"It's going to be special because David spent so much time there. He is eager to see everyone at Old Trafford. It's been a special place for him. When he left United I was devastated. Returning will be great because he's still a United supporter. He will be choked by it all.
"He loves it in Milan. He enjoys the football and playing alongside players like Ronaldinho. But there are a lot of good players at Old Trafford. It will be a weird feeling. Half of me wants AC Milan to win while the other half will be rooting for Manchester United."
