Oxford caretaker boss Mickey Lewis had no arguments about his first defeat in charge, a 3-2 loss at Newport.
Despite goals from James Constable and Alfie Potter's first since a return from injury their unbeaten away record in League Two, which stretched back to April, came to an end.
Lewis said: "I thought we were beaten by the better side.
"Sometimes you have to give credit to the opposition, they were a lot sharper to the ball than us. Even though we gave it a right good go at the end and nearly nicked something, in all honesty it would have been very unjust.
"In the first half the goal was the only real bit of quality we showed.
"I thought we were going to get to half-time in front but they scored just before the break and in the second half they dominated.
"But we've been on a great run and in the real world as much as we would have liked it to continue it was always going to come to an end at some point.
"We can look back on it with pride and now we need to build another one."
