Roberto Martinez was naturally delighted to have claimed the scalp of FA Cup holders Portsmouth

The Swansea City manager witnessed his side turn in a magnificent display to end Portsmouth's grip on the trophy at Fratton Park and could not hide his delight as the supporters sung his name at the final whistle.

"It wouldn't say it was a fluke, we were the better side over the 90 minutes," Martinez told BBC Wales.

"It was a great performance to the end because we had to hold our concentration and our focus.

"To get the two-goal cushion was important.

"The players have worked extremely hard and success in football doesn't come as an accident

"(The win) was more than anything the positive feeling of being able to come to a Premier League environment and be ourselves.

"That's what we were looking for and I'm delighted we've been able to do that because to say we've been the better side against a very good Portsmouth side, I think it tells you a lot about the performance.

"You can see we are getting better and that's credit to everyone at Swansea City.

"Portsmouth threw everything, they had nothing to lose, they had to chase the game and they've got a player who's been moving around in world football for £26m so you are going to expect them to get chances

"But the way you defend, the way you make the decisions and the way you take the challenges, I couldn't be prouder of the players, and that's another clean sheet.

"I thought they (the fans) were fantastic today from the first minute and they were our 12th man on the pitch."
