Middlesbrough have finalised the signing of Argentine striker Emmanuel Ledesma on a three-year deal.
The 24-year-old was a free agent after his contract with Walsall expired earlier this summer.
Speaking last week, Middlesbrough manager Tony Mowbray spoke highly of Ledesma's ability.
"Having watched him last year, we know he's a talented boy," he said.
"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."
Ledesma is the fifth player to arrive at the Riverside so far this summer following the additions of Grant Leadbitter, Stuart Parnaby, Christian Burgess and Jonathan Woodgate.
