Arsenal set up an FA Cup fourth-round tie at Manchester City after cruising to victory over League OneOxford United at Kassam Stadium.
Mikel Arteta's Premier League leaders were frustrated in the first half by a well-organised and disciplined Oxford side before eventually overpowering their opponents.
Fabio Vieira was Arsenal's creator-in-chief, sending in a perfect free-kick for Mohamed Elneny to head past Oxford goalkeeper Eddie McGinty in the 63rd minute before playing a perfect pass for Eddie Nketiah to finish calmly finish seven minutes later.
Oxford, who had battled so hard, were now struggling to cope with Arsenal's attacking threat and Nketiah was on the mark again after 76 minutes with a delicate chip over McGinty from Gabriel Martinelli's pass to confirm that powerhouse meeting with City at Etihad Stadium.
Arteta later said, "It is always tough to win in this round. You have to be patient and we were patient and found the right openings.
On Nketiah, he added: "It is what we want from every player. I am delighted. You have to be scoring goals and he is doing it."
