Swansea boss Brendan Rogers says Scott Sinclair is on the edge of an England Under-21 call-up following his hat-trick against Peterborough.
Sinclair, who joined City for £500,000 from Chelsea last month, booked the Swans a spot in the fourth round of the Carling Cup thanks to his clinical treble at London Road.
And his recent performance, including his starring role in Tuesday's 3-1 win, has brought him to the attention of Young Lions boss Stuart Pearce.
"I contacted Stuart and asked if Scott was on their radar," said Rodgers.
"To be fair to Stuart, he told me they had been hearing all about him and the scouts had been watching him.
"He is still blossoming. He gets better with games and is really maturing. There is still a lot to come from him. He is still developing.
"Every game he plays, it looks like he is going to score. He knows he has got a lot to learn but he is a good kid.
"I know the boy well and his mentality. We kept in touch when I left Chelsea. He was a big talent when he broke on the scene at 17 but then went out on loan at teams where he did not play.
"When you get to 20 or 21, you need to go. Scott's career was out on loan at clubs in difficult moments. He was not getting the game time.
"He needed to find a home. I spent hours on the phone to him and convinced Swansea was the place for him to be. He can help the club and help himself.
"He has had two years resting. He is so fresh, he wants to play every game. He wants to score goals and at this moment in time in his career, he will tell you, he wants to play football. He is loving it at Swansea."
Sinclair opened the scoring in the fifth minute only for Peterborough's Craig Mackail-Smith to level a minute later.
Sinclair restored Swansea's lead second four minutes before the break and completed his treble in the 78th minute.
Rodgers added: "We prepare for every game and want to win it. We saw that tonight. We worked hard and our control and domination was really good.
"Peterborough are a very good side and could go straight back up to the Championship, which I hope they do."
Posh boss Gary Johnson admitted his frustration with referee Nigel Miller, who refused to award the home side a penalty, despite several appeals.
"We are angry," said Johnson. "It spoilt the game because I don't think he wanted to make those kind of decisions.
"If it was once or twice, you might be unlucky, but you are not unlucky five times.
"I felt we didn't quite finish the game well enough. The last 20 minutes, we were demoralised."
