Prior to kick-off, he was taken to hospital as a precuation after falling ill. It was confirmed on Monday that the 84-year-old was recovering well following his worrying episode at the Theatre of Dreams, with Ferguson in good spirits and feeling considerably better.
Owen opened up about his exchange with his former manager which took place before Sunday's match. He told talkSPORT: "I spoke to him, I was on the phone to him for forty minutes that morning.
"We're talking about football. We're talking about horses. As I say, he's got horses here [at his Manor House Stables]. Most Saturday mornings, he gives me a call, and we go through all the horses for the day, and we share what we know and things like that.
"We might have actually, we might have his horse running on Friday at Chester. So yeah, I speak to him regularly, and he sounded absolutely brilliant, sharp as a tack as normal. We were talking a lot about Scottish football and what was happening up there.
"So it was such a shock to hear, obviously, that the next day he was taken unwell, but hopefully it's not too serious."
Following United's victory over Liverpool, Red Devils interim manager Michael Carrick expressed his support for Ferguson. Carrick spent several years playing under Ferguson the legendary Scottish boss.
The United temporary head coach said: "I haven't got any updates so I don't know the latest. I did hear about it before the game so I was aware about that.
"All I can say is I was very affected by the news. I hope he is all right. We hope him to be in good shape and we we wish him all the best and hopefully the result gives him a good boost."
