City were unable to reverse the form guide as they slipped to a 0-4 defeat at unbeaten league leaders, Oxford City, who made it seven wins from seven games.
The game was staged at the hosts' impressive first team stadium but the early kick-off seemed to affect the visitors as they were sluggish against their opponents who zipped the ball around and probed for openings - City perhaps fortunate to end the first quarter on level terms.
They seemed more awake by the second quarter, grew into the game and threatened several times on the counter, getting shots off but without really testing the Oxford keeper as the first half ended goalless.
The home side continued to retain the ball the better of the two sides and broke the deadlock in Q3 when they raced clear down the left and squared to score. A second goal soon followed - one that really should have been avoided - as City sloppily conceded a free header from a corner.
To their credit, the visitors battled to the final whistle and threatened the home goal on several occasions in Q4 with shots by Lewis Corbett and Declan O'Shea with the best chance falling to Jesse Asomugha which was saved. With City piling forward to pull a goal back, Oxford exploited the space and scored twice more to run out worthy victors.
