Espanyol have completed the signing of Chelsea striker Ben Sahar on a four-year deal.

Sahar failed to establish himself during his three years at Stamford Bridge and had loan spells at QPR, Sheffield Wednesday, Portsmouth and De Graafschap.

And, despite interest from Ajax, he has now secured a permanent deal at La Liga side Espanyol.

The 19-year-old Israel international has Polish citizenship, allowing him to play for EU sides without obtaining a work permit.
