Swansea have completed the signing of central defender Albert Serran from Espanyol B in a deal worth £80,000.

The 23-year-old has penned a long-term deal with the Swans - the club have not disclosed the exact length - and Serran becomes boss Roberto Martinez's sixth signing of the summer.

"Albert is perfect for the British game," said Martinez.

"He is a committed and aggressive defender and that is the type of player we want at Swansea.

"He could have taken an easier option by signing closer to home for a La Liga club - and even had the option of going to Poland - but he wants to play in the Premiership with Swansea."
