Mexico international Efrain Juarez has left Celtic to sign with Real Zaragoza on-loan.

The versatile 23-year-old, who can operate in midfield or defence, made the move to Scotland after representing his country at last summer's World Cup.

But he struggled to establish himself as a regular in Neil Lennon's side, making 11 starts and nine appearances off the bench.

Juarez will be reunited at Zaragoza with compatriot Javier Aguirre, who coached Mexico at the 2010 World Cup.
