Sunderland have confirmed that Paraguay international midfielder Cristian Riveros has joined Turkish club Kayserispor on a year-long loan deal.
Riveros, who arrived on Wearside on a free transfer from Mexican outfit Cruz Azul last summer when he signed a three-year contract, has made just 14 appearances for the club, only seven of them in the starting line-up.
Manager Steve Bruce said: ''Cristian wants to play regular football and hopefully he will be able to do so in Turkey. We wish him all the best.''
Bruce has enjoyed significant success in the past with recruits from central and South America, but has seen Riveros, compatriot Paulo da Silva and Argentinian defender Marcos Angeleri find the going tough on Wearside.
Riveros is one of a series of players the club will look to move on this summer, either permanently or on loan, as Bruce makes room for his summer signings.
