The 76-year-old was admitted to the Salford Royal Hospital for emergency surgery.
On Thursday, Manchester United posted a video on their social media platforms, with a message from Ferguson.
“Hello just a quick message, first of all to thank the medical staff at Macclesfield, Salford Royal and Alexandra hospitals.
“Believe me, without those people, who gave me such great care, I would not be sitting here today. So thank you from me and my family. Thank you very much.
“It has made me feel so humble, as all the messages I have had from all over the world wishing me the best and the good wishes do resonate very, very strongly with me, so thank you for that support you have given me.
“Lastly, I’ll be back later in the season to watch the team. In the meantime, all the best to Jose and the players. Thank you very much,” he said. SHARE THIS STORY USING ANY OF THE BUTTON BELOW ⬇ PLACE YOUR TEXT ADVERT BELOW ⬇⬇⬇
