It looked like Real Madrid dismantling a poor second division Spanish side.
You could have been mistaken for thinking you were watching Los Blancos as Swansea, in their all-white kit, crushed League Two’s Notts County.
The Swans were 4-1 up by half time and banged in another four goals in the second half to thump the lower league opposition – but every goal they scored was a pleasure to watch.
This performance made us think back to the heady days of Brendan Rodgers’ time in Wales when the team played beautiful football and drew comparisons to the way Barcelona played with their tiki-taka passing.
Against Notts County Swansea demonstrated that Carlos Carvalhal is a miracle worker and has restored the confidence in a team that contains genuinely quality.
In the 18th minute Tammy Abraham broke the deadlock with a real poachers’ finish as he calmly turned a whipped cross home.
Less than two minutes later Nathan Dyer burst clear and coolly curled the ball past the onrushing keeper to double Swansea’s lead.
A slick passing move then culminated with Dyer finessing the ball into the bottom corner from the edge of the area.
Then Abraham got his second of the night with a similar finish to the third, using his right foot to bend it into the top corner after Swansea’s passing left Notts County chasing shadows.
Kyle Naughton added a fifth just after half time before Wayne Routledge got involved on the act with an arcing shot from 18 yards.
With an hour on the clock Tom Carroll turned into Lionel Messi as he cut onto his left and buried a great shot into the very top of top bins.
Youngster Daniel James owes Abraham a pint as the England striker put it on a plate for the 20-year-old to smash into the back of the net and complete Swansea’s biggest ever FA Cup victory.
Couple this win with consecutive league triumphs over Liverpool and Arsenal and a draw away to Leicester and you start to think that it is Carvalhal we should be calling the new Mourinho not Marco Silva.
The Portuguese boss has lost just once in his nine-game tenure in Wales but more impressively he has turned Swansea back into the entertaining, free-flowing team that is glorious to watch.
No doubt Everton are already lining up a bid.
