Former Manchester United coach Sir Alex Ferguson has described fellow club legend Sir Bobby Charlton as a “tower of strength” for him in a heartfelt tribute.

Sir Bobby, who was one of the greatest English footballers to ever play the game, died last Saturday (October 21) at the age of 86.

His illustrious career saw him win the World Cup with England and the European Cup with Manchester United before serving the club as a director and ambassador.

He remained a prominent figure at Old Trafford throughout Sir Alex’s glittering 26-year reign as manager, which began in 1986.

Sir Alex Ferguson's heartfelt tribute to Sir Bobby Charlton

In a eulogy to be published in the matchday programme for Sunday’s (October 29) derby fixture between United and Manchester City, Ferguson reflected on his appointment and the “personal connection” he had with Sir Bobby.

Sir Alex said: “The directors came to meet me in Glasgow and asked what my vision was for the job.

"I said I would take the same approach I had at Aberdeen, by looking to build up the whole club, not just the team, and that I would do that by developing young players.

“As I was explaining this, I saw Bobby nudge one of the other directors and he said, ‘that’s what we want’. He’d made his mind up. From that moment on he was a tower of strength for me.

“It’s no surprise to me that we’ve seen tributes to Sir Bobby from everywhere in the world, on every TV channel and in every newspaper, because he was without question the greatest English player of all time.

“People loved him because of all those thunderbolt goals, but it was more than that. My dad used to say that humility in success is a sign of greatness, and that was Bobby.

“He never used to boast about his own achievements; it was always about the team and the club.”

Sir Bobby's death came soon after that of Ferguson’s wife, Lady Cathy.

He added: “I am so sorry for Lady Norma (Charlton), who was always by Bobby’s side, especially as his health declined, and my thoughts have been with the whole family these past few days.

“Unfortunately, I have also suffered the painful loss of my beloved wife, Cathy, this month, and I want to thank the club, the fans, and everyone who has sent me their condolences.”
