Sir Alex Ferguson said today's Manchester United trophy parade topped the celebrations in 1999, when the club won an unprecedented treble.
Speaking to the thousands of supporters who gathered to celebrate the club's title success, he said: "What a turnout, absolutely fantastic.
"I thought that '99 (when Manchester United won the treble) could not be beaten but you've beaten it today, absolutely fantastic.
"All of you thank you for the fantastic support, we're proud of you and the players are a magnificent bunch of lads and I hope I'm here to witness this many, many times again.
"So, well done, good luck."
