Sunderland have completed the signing of midfielder Arnau Riera from Barcelona.
The 24-year-old, who captained Barca's B team last season, has signed a three-year contract with the Black Cats after impressing during a ten-day trial on Wearside.
Manager Niall Quinn told Sunderland's official website: "Arnau is an exciting player. He has fantastic lungs, is a playmaker but can also tackle.
"He's the type of player you need to be to come to Sunderland; he ticks all the boxes. He's a fine, athletic player.
"I've talked about us needing creativity and he's a player I think will create."
Riera is likely to go straight in to the team for Saturday's Championship clash with Plymouth, as long as his international clearance arrives in time.
