Sunderland have announced the signing of Holland defender Patrick van Aanholt from Chelsea.
The left-back has joined the Black Cats on a four-year deal for an undisclosed fee.
Van Aanholt, 23, is Sunderland's fourth new recruit of the summer, following on from the arrivals of Billy Jones, Costel Pantilimon and Jordi Gomez.
His time with Chelsea, for whom he made a total of just eight appearances, has featured a series of loans including stints with Coventry in 2009, Newcastle in 2010 and Leicester and then Wigan in 2011.
He has spent the last two-and-a-half seasons on loan at Dutch outfit Vitesse Arnhem and has been capped twice at senior international level.
Van Aanholt was named in Louis van Gaal's 30-man provisional Holland squad ahead of this summer's World Cup, but did not make the final 23-man cut for the tournament in Brazil.
