Sunderland have opened talks with Sevilla over a £7million move for Vicente Iborra.
The 28-year-old has been a target for Swansea City and West Bromwich Albion in recent weeks.
A 6ft 3ins defensive midfielder who is good on the ball, Iborra can also play in a more advanced role.
He made 47 appearances last season and scored nine goals, including the winner against Barcelona in October.
