Player with good potential. Typical Spanish (La Masia) player with great passing and technique. Also, good crossing of the ball. He is noticeably faster than Suso, but Suso has better control (although its easier to control the ball when you are moving slower...)
His natural position is on the right wing, and he is best there, but make no mistake if he comes here he will be playing LW where we can utilize his goalwards crosses. Just look at the damage Suso is able to make with his inswinging crosses.
Problem could be his mentality, since he "failed" with 3 different coaches (Martinez could count as success as he played well, but Everton struggled), but thats on Montella to work out and get the best out of him.
