Swansea boss Roberto Martinez spoke of his pride after his Coca Cola Championship side dumped holders Portsmouth out of the FA Cup with a dazzling 2-0 victory at Fratton Park.
Nathan Dyer, on loan from bitter Pompey rivals Southampton, hit a glorious 27th-minute strike before Jason Scotland stroked home a penalty to leave Pompey's cup defence in tatters.
"Nathan was a threat all of the time," said Martinez. "Mentally he'd run out of gas at the end, as you'd expect, but he will fulfil his potential."
He added: "I've always said he has to play in the Premier League and slowly he's getting there. He's had a few problems in the past. He's desperate to enjoy his football. He's a lively character in the dressing room and is fresh.
"The crowd reaction maybe added an extra spice to his game, but the real difference was his hunger. He's learned from his mistakes in the past and is ready to fulfil his potential."
Swansea dominated the first half but were forced to weather Pompey's attempted fightback after the interval. Goalkeeper Dimitrios Konstantopoulos starred as the home side were kept at bay and Pompey boss Tony Adams had no complaints with the result.
"In the first half we were outplayed and outfought," said the former England skipper.
"I did warn the players we were up against a very good Swansea team who like to pass the ball and that we would be in trouble if we weren't prepared.
"Sadly, I was proved right. Without that fight you go out of this competition.
"We didn't deserve to be 2-0 down at half-time but we didn't play well in the first half either. We were very poor. It's disappointing to go out of the FA Cup, no matter what round it is. You have to put defeats like this to bed as quickly as possible."
