Swansea City have signed England Under-20 defender Nathan Wood from Middlesbrough for an undisclosed fee.
The centre-back played two cup games for Boro last season, plus one Scottish Premier match on loan at Hibernian.
"You look at the facilities... the players, the fans, the stadium, everything - it's a Premier League club," Wood told the Swans website.
"That's where everyone wants to see Swansea and there's no point setting low goals, you should aim to be the absolute best."
Wood is Swans head coach Russell Martin's first signing of the summer transfer window.
