Swansea took an early lead against Oxford in the FA Cup through a superb goal from Jefferson Montero (you can watch lower down the page.)
From there on, it was all about Oxford, and in particular, Kemar Roofe.
The League Two side got an equaliser through Liam Sercombe from a penalty.
In the space of ten minutes early in second half, Roofe gave his side the lead and then a two goal advantage.
His first was a perfectly placed shot after he had cut in from the left.
His second, which made it 3-1, came from a swift counter-attacking move.

Here's the Montero goal, meaningless now really. Still, pretty to look at.
