West Ham United have pulled out of a deal to sign Argentine forward Milton Caraglio, skysports.com understands.
The 22-year-old plays for Rosario Central and was lined up by Avram Grant to bolster his strike-force.
He linked up with West Ham earlier this month and played in their friendly at League One side Milton Keynes Dons.
However, it is now understood that Caraglio failed to pass the stringent medical that West Ham put him through.
As such West Ham have opted not to pursue the deal and the striker has now returned to Argentina, although there is reported interest from Italy.
