Sir Alex Ferguson visited Denis Law up to three times a week at his care home, before his friend's death aged 84 on Friday.
The legendary coach will be present at Sunday's match at Old Trafford, where Manchester United faces Brighton, to witness the tributes to the forward, which will culminate with a minute of applause.
Ferguson, 83, made frequent trips to see his fellow Scots at the Cheshire-based home, a short trip from his £1.2 million home in Goostrey, Cheshire East, according to the sun.
On Friday night, Law's family announced his death, which came after a grueling three-year battle with dementia.
Law, who revealed in August 2021 that he had been diagnosed with Alzheimer's and vascular dementia, is one of the United Trinity immortalized in a statue at Old Trafford alongside George Best and Sir Bobby Charlton. To fans, he was simply known as The King.
In the past, Ferguson revealed that he idolized Law as a player, and once recalled the moment they met.

Law, posing alongside Sir Alex Ferguson and Sir Bobby Charlton, formed United Trinity with Charlton and George Best, and the trio have a statue in their honor outside Old Trafford.
“Denis Law was my hero as a player, I idolized him,” he said.
'When I first met him, I was very excited. It was at a match in Paris, where he had played the first half and afterwards we went to have tea.
'I thought: “This is it, I've done it, I'm having a cup of tea with Denis Law!”
“For me, he epitomized everything a Scot means. He was bold and brave, he had that bravery and he had style. “He was a really fantastic footballer.”
A statement from the Law family read: “It is with great sadness that we inform you that our father Denis Law has sadly passed away. He fought a tough battle but is finally at peace now.
'We would like to thank everyone who contributed to his well-being and care, in the past and much more recently. We know how much people supported and loved him and that love was always appreciated and made a difference. Thank you.'
Winner of the Ballon d'Or in 1964, Law won the European Cup, two English titles and the FA Cup in his 11 years at Old Trafford.
He is United's third all-time top scorer behind Wayne Rooney and Charlton with 237 in 404 games, and Scotland's joint top scorer with 30 goals in his 55 internationals.

United also issued a statement on Friday night, saying: “Everyone at Manchester United is mourning the loss of Denis Law, the king of the Stretford End, who has passed away at the age of 84. With 237 goals in 404 appearances, he will always be celebrated as one of the club's greatest and most beloved players.
'The top scorer, his style, spirit and love of the game made him the hero of a generation. Our deepest condolences to Denis' family and many friends. His memory will live forever.”
Law was the sixth member of United's European Cup-winning team with Sir Matt Busby to suffer from dementia.
Charlton, who died in October 2023, Nobby Stiles, Tony Dunne, David Herd and Bill Foulkes were also diagnosed before they died.
