Chelsea youngster Ben Sahar has agreed a four-year deal with Espanyol after struggling to break into the first team at Stamford Bridge.
The 19-year-old Israel international moved to the Blues three years ago but has failed to make a first-team start for the club although he has come off the substitute's bench on five occasions.
He has also spent time on loan at QPR, Sheffield Wednesday, Portsmouth and De Graafschap in the last two seasons.
A statement on the Spanish side's official website read: "Although there was an offer from Ajax, the youngster wanted to move to La Liga instead of returning to the Dutch championship, where he has played for De Graafschap."
Espanyol also continue to be linked with Celtic's Japan international Shunsuke Nakamura who is believed to be close to agreeing a deal with the club.
