The Iceland midfielder struck the crossbar in the second half and it looked like our dominance might only yield one point at Cardiff City Stadium.
But as the clock ticked into the 93rd minute, substitute Erik Lamela won a header to Lewis Holtby, he rolled the ball back into Erik’s path and he crossed for Paulinho to backheel home from close range.
“It was amazing,” said Gylfi. “It’s the best way to win football matches, goals in the last minute. We had lots of chances, lots of shots, they defended well and it was great to see that goal finally go in.
“All the bench wanted to join in the celebrations.
“The main thing was to get the three points. It’s a difficult place to come to, you saw that when they beat Manchester City. To keep another clean as well, that’s fantastic for the team.”
The players didn’t have too long to reflect on Sunday’s win as preparations begin for Tuesday night’s trip to Villa in the Capital One Cup.
“It’s always tough at Villa Park, they have good young players but we’ve got the players to go there and get a result,” added Gylfi.
“We want to do well in every competition and this is no exception.”
