The keeper joins on a four and a half year deal having signed on a free transfer after bought himself out of the remaining 18 months of his contract abroad. It is the first time the keeper has left Spain and is indicative of the pull that Leeds, and probably the tactical genius of our manager can have.
Bailey Peacock-Farell is expected to make way for the new signing, having played 31 times. There is no doubting the youngsters ability. He has pulled off some outstanding saves this season, however he is inexperienced and has made a couple of errors, and having an experienced professional like Casilla at the club will not do his development any harm.
The signing not only gives Leeds strength in goal for the promotional push, but secures a healthy future for the club in between the sticks.
