Leam Richardson was crestfallen after his Accrington side twice took the lead only for Oxford to snatch a 3-3 draw in the FA Cup on Saturday.
Michael Raynes scored in the last minute of time added on to earn Oxford a second-round replay after Lee Molyneux's 91st-minute free-kick appeared to have won it for Accrington at the Crown Ground.
Stanley striker Craig Lindfield cancelled out Jon-Paul Pittman's opener for Oxford and the game then burst into life with 10 minutes to go when James Beattie scored a wonder goal from 30 yards, hitting it first time into the top of the net before James Constable fired low into the bottom corner with four minutes left.
"To score so close to the final whistle and then only draw, is so disappointing, but we do need time to reflect on it," said Richardson. "We went in front twice and so are down about not winning, but we are in the third-round draw and we are looking forward to that.
"We scored two superb goals through James Beattie and Lee Molyneux and they would deserve to win any game, but it didn't happen.
"It was a fantastic 90 minutes - it was great for the neutral, but not for the two managers or the fans. We are a young team and we have to learn to become better."
