Abraham registered his brace on the brink of halftime after Nathan Dyer had helped himself with a pair of his own with Noor Hushin scoring the Magpies’ only goal of the night.
Further strikes from Kyle Naughton, Wayne Routledge, Tom Carroll and Daniel James sealed an emphatic victory for Carlos Carvalhal’s resurgent side.
Much of the pre-match talks had centred on his young striker, whom prior to his 18th-minute goal had failed to hit the target in 825 minutes. The Portuguese gaffer would definitely be delighted with his response - as he also added two assists to his showing - which was instrumental in ushering the Swans to the Round of 16 of the cup competition.
Abraham, now with scored seven goals in all competitions, will hope to get another opportunity when the south Wales outfit host Burnley in Saturday’s English Premier League fixture.
