Alex Ferguson was at Old Trafford to watch Manchester United on Saturday for the first time since his health scare in May.
The 76-year-old was pictured arriving at the ground ahead of United's match against Wolves in the Premier League.
Ferguson has largely remained out of the public eye following a brain haemorrhage that required emergency surgery.
He appeared in a video in July to thank hospital staff for saving his life and is sure to receive a rapturous reception from fans of the club he led to 13 league titles.
United are seeking a fourth successive competitive victory following wins over Burnley, Watford and Young Boys in the Champions League.
Ferguson, who will watch on from the directors' box, said he had been overwhelmed by the flood of supportive messages during his recovery.
"It's going to be a bit emotional for me when the game gets started and things like that," the Scot told MUTV.
"It had to happen sometime. I've been looking forward to it. The important thing was getting the right time and the right rest before I came to a game.
"It was unbelievable. There were thousands of cards. They kept arriving at Salford Royal Hospital and of course I'd left by that time, but they kept coming.
"The number of emails and texts and personal cards to the house, it really was amazing. I was overcome by it."
