The 22-year-old joined the Baggies on loan in February and made three starts and seven substitute appearances as they clinched the Coca-Cola Championship title.

Moore, who won his fifth England Under-21 cap in March's goalless draw with Poland at Molineux, has penned a deal which will keep him at Albion until at least the summer of 2011.

The deal also has included a further year's option in the club's favour and the eventual fee could rise to £3.5million depending on performance-related criteria.

Moore is a product of Villa's youth system and was a prolific goalscorer for their academy and reserve teams. Alongside brother Stefan, he was part of the club's FA Youth Cup-winning side in 2002.

Moore followed his brother into the first team reckoning at Villa Park and scored his first top-flight goal in the 2-0 win over Middlesbrough in March 2005.

The 2005-06 season proved his most productive in a claret and blue shirt as Moore scored eight Premiership goals in 16 starts, including a hat-trick at Middlesbrough in February 2006.

Moore also got off to a flyer in 2006/07, scoring twice in the first eight games, only for a shoulder injury to rule him out for six months.

But he returned to notch twice in half a dozen late-season substitute appearances. Moore scored twice in nine starts for Villa last term.

In total, Moore made 41 starts for Villa, plus 57 sub appearances, scoring 15 goals. He also scored four goals in six appearances during a loan spell at Wycombe in 2003/04.

Albion have also confirmed they are converting Do-heon Kim's loan move into a permanent deal after agreeing a fee of £550,000 with his club Seongnam Ilhwa Chunma.

The 25-year-old has agreed personal terms on a two-year contract with a further year's option in the club's favour.

Kim, who originally joined the Baggies on loan in January, will complete his move to The Hawthorns on June 1.

West Brom manager Tony Mowbray said: "The four months he has already spent with us will have been a big benefit to him in terms of integrating with the squad and overcoming the language barrier.

"I'm now looking forward to working with Kim next season."

Kim made one start and six substitute appearances last season, including coming off the bench to score his first goal for the club on the final day at QPR as West Brom clinched the Coca-Cola Championship title.

In their third bit of business of the day, Albion have taken up the option of extending Czech keeper Michel Danek's loan from Viktoria Plzen for a further six months.
