Oxford City stunned a youthful Cheltenham Town side with a 3-0 win at Whaddon Road to march through to the FA Trophy third round.
The Robins, who on the same night lost top spot in the National League with Forest Green winning to leapfrog them, fielded a much-changed line-up from the side than won at Dover Athletic 48 hours earlier.

And they were given a masterclass in finishing by National League South side Oxford who netted through former Cheltenham loan player Marlon Jackson, top-scorer Bradley Bubb and Darren Pond, who later limped off injured, to win the second-round replay.
Elliot Osborne scored twice as Nantwich Town beat Bradford Park Avenue 5-0 to reach the last 16.
Matt Bell gave the Dabbers a slim lead at the interval, but they ramped up the pressure in the second half to reach round three comprehensively.
Sam Hall doubled their advantage and, after Osborne bagged his brace, Matty Kosylo rounded off the scoring.
Oxford City will travel to Woking in round three, while Nantwich are set to meet Stourbridge.
