Michael Laudrup heaped praise on his players following the 3-0 win against Valencia in the Europa League.
The Swans produced a complete performance to stun the home side, who were reduced to ten men after just ten minutes.
Valencia defender Adil Rami was shown a straight red card for a professional foul on Wilfried Bony, and the striker gave the visitors the lead shortly after.
Chances followed to increase the lead, but Michu doubled the Swans’ advantage in the second half before Jonathan de Guzman wrapped up the win – and top spot in Group A – with a stunning 30-yard free kick.
And Laudrup was understandably delighted with his players as Swansea marked another historic night in the club’s history.
“It was a fantastic game,” he said. “Of course the red card was an influence - but we dominated from the first minute to the last.
“It could have been more than three and I’m very pleased to beat a club like Valencia. It was our fifth game in Europe – and we were facing a big team.
“But I’m just so pleased for everyone. Not just the fans, but for the players as well. It is great to see that even if we have players without international experience, then there is no problem.
“We had a lot of fans here and I’m sure they had a night to remember. These are great experiences, and to win the first game in the group is a fantastic start.”
There is no let up for the Swans as they return to domestic action in less than 48 hours time when they travel to Crystal Palace.
And Laudrup wasn’t getting carried away ahead of the next two group games at the Liberty Stadium against St Gallen and Kuban Krasnodar.
“We now have to change competition, as Sunday’s game is important,” he said. “But if we don’t win the next European game at home then we are back to where we started.
“We can’t enjoy this win for too long as we look ahead to Crystal Palace, because it is a very important game for us again.”
Swans captain Ashley Williams missed the win over Valencia with an ankle injury, and Laudrup was unsure about his availability for Sunday’s clash at Selhurst Park.
“We’ll have to see about Ashley,” he said. “Angel is not injured, but I wanted to give Dwight (Tiendalli) a full game because we only have three full backs at the moment with Neil (Taylor) injured as well.”
