Oxford are chasing FA Cup history on Saturday at Middlesbrough, with boss Michael Appleton targeting one-off and sustained success.
United are in the last-16 for the first time since 1993-94 and a win at Boro would ensure their best run in the competition since reaching the quarter-final against Preston in 1963-64.
Oxford beat Rafael Benitez's Newcastle 3-0 to advance to the fifth round and have the opportunity to match the run of 53 years ago and move within a game of a Wembley semi-final.


'We'll make the players aware of the stats and the facts,' Appleton said.
