Emmanuel Ledesma has completed his move to Championship club Middlesbrough.
The 24-year old Argentine midfielder has signed a three-year deal with the Teessiders, joining as a free agent after his short-term deal with Walsall finished at the end of last season.
"Having watched him last year, we know he's a talented boy,” Boro boss Tony Mowbray told the club’s official website.
"He's a centre-forward who drops into midfield and links the play up well. He's left-footed and has a real work ethic."
