Chris Wilder couldn't hide his delight as his Oxford side sent their supporters into raptures with a 2-0 derby victory over Swindon.
The League Two leaders' 10-game winning run was ended as Oxford overcame the early loss of striker James Constable to register a victory against the odds. He was sent off in the 11th minute for elbowing Joe Devera, but the U's scored twice in quick succession through Asa Hall and Oli Johnson.
Wilder said: "It was a massive effort from my players because Swindon are a real good side.
"We rode our luck at times, and we were indebted to some great defending and great goalkeeping, especially not only going down to 10 men but going down to 10 men that are not regulars in the side. I would like us to be a lot closer to Swindon in the league. To my mind I have no doubt they will go up."
Wilder was disappointed, though, with the Swindon players' reaction to the foul on Devera that ended in Constable being sent off.
"It was a poor effort that players ran 50 or 60 yards to get involved and put pressure on the referee," he said. "I saw 10 or 11 players run over to the referee."
