Swansea have secured the services of Joe Allen on a three-year contract.
The 17-year-old midfielder has signed his first professional contract, tying him to the club until 2010.
Allen was called up to the Wales Under 21 squad last week and then produced an impressive performance on his full debut against Walsall on Tuesday.
The 5ft 6in youngster, who set up the opening goal in the 2-0 Carling Cup victory, told Swansea's official website: "It's what dreams are made of."
Manager Roberto Martinez added: "I'm delighted we've secured the services of such an exciting talent.
"It's fantastic to have such Welsh talent in the squad and I'm sure he has a bright international future ahead of him and an exciting career with Swansea City."
