Alan Judge heralded the re-run of the 1986 Milk Cup final at the Manor "an absolutely fantastic day".
More than 3,500 fans turned out to see virtually the entire Oxford team take to the pitch as they recreated the club's greatest-ever day against Queens Park Rangers.
And Judge, who organised the match to raise money for cancer charities, was overwhelmed by the response of both the players and supporters.

"To have so many people here to watch was wonderful," he said.
"We thought they would be one or two hiccups on the day, but everything went smoothly, so we are all delighted."
And Judge was quick to pay tribute to people who had given up free time to help organise and be part of the day.
"I cannot thank the staff at the club enough. They have given up their free time and have helped me set things up for no payment whatsoever. The response from the players has also been fantastic.
"In some cases, they have travelled quite a distance to take part, and they are doing it all for free, which is great."
The match itself ended in a 4-4 draw, but the result did not matter, it was a special day all round, with heroes from the past returning to the Manor for the final time.
"It's amazing because the players are getting old, putting on weight and going grey, but you could see the class they had out there today," Judge added.
"You never lose what you had, and it was clear they were a fantastic bunch of players."
Jim Smith, who led out Queens Park Rangers, said the support of the fans was unbelievable.
"It was a fantastic day and great that charity is going to benefit a lot from it all," Smith said.
"Alan deserves a lot of credit for organising it - it was a great day."
