Former United boss Ferguson, who delivered 13 Premier League titles to Old Trafford during his reign, said of Guardiola: "Pep! I am absolutely delighted to welcome you to join the prestigious LMA Hall of Fame 1,000 Club. Your deep love and passion for the game has always been so evident and you should be very proud of the indelible impact you continue to have across the global game.
"Reaching 1,000 matches and achieving such longevity in football is a landmark that can never be underestimated and, to continue to deliver league, Champions League and domestic cup titles in three of Europe’s most competitive leagues is outstanding. I look forward to celebrating with you at an LMA gala dinner to formally induct you into the LMA Hall of Fame 1,000 Club."
LMA Chief Executive Richard Bevan OBE added: "Pep has dedicated his entire career to achieving excellence, driven by an unmatched will to win and a world-renowned style. His achievements and success in Spain, Germany, and England are unprecedented, and his influence continues to shape the game for future generations.
"Pep’s achievements rank among the most remarkable in football history, and on behalf of the entire League Managers Association, I offer my sincerest congratulations to him on reaching such a prestigious milestone."
