Swans ease past Wednesday into quarters
Swansea 2-0 Sheffield Wednesday
Swansea reached their first FA Cup quarter-final since 1964 with a 2-0 home victory over Sheffield Wednesday.
Jordan Ayew, on as a half-time substitute, scored the opener before Nathan Dyer settled matters 10 minutes from time.
Dyer raced on to Tammy Abraham's pass to slot his shot between the legs of Owls goalkeeper Cameron Dawson and ensure Swansea manager Carlos Carvalhal would taste victory against the club he left in December.
Those second-half goals saw Swansea through on a night when the temperature dial had fallen below zero at kick-off.
Twice the Swansea goal was threatened in a matter of seconds with Kristoffer Nordfeldt pushing away Jacob Butterfield's well-struck shot from 18 yards.
The Swedish goalkeeper also had to react quickly as Lucas Joao sent the loose ball back into the six-yard box, with Jordan Rhodes close to a telling touch.
Nordfeldt then held Joao's effort after the Portuguese switched the ball back on to his left-foot with Wednesday sensing a breakthrough and an upset.
Swansea responded with wayward attempts from Sam Clucas and Abraham, and Carvalhal blinked at half-time with Martin Olsson and Ayew replacing Ki Sung-yueng and Wayne Routledge.
Carvalhal's call paid off 10 minutes after the re-start as Carroll strode forward with purpose, striking both posts with a rasping effort, before Ayew dispatched the rebound for his ninth goal of the season.
Abraham played a decisive role in Dyer's decider as Swansea removed the last representative of the Sky Bet Championship from the competition.
