The 23-year-old scored just five goals and provided three assists in all competitions as Villareal struggled last season leaving some fansconcerned about the player.
But Balague has no doubts that the midfielder will be a huge hit and reckons he is an outstanding signing for the club.
He took to Twitter to confirm claims that the deal for West Ham to sign Fornals is imminent and said: “Brilliant signing, 23-years-old. In the mould of a FCB (Barcelona) midfielder, genius in the pass, drives the ball with quality.
“Big gaps in concentration without ball but can be added to his game. Winning mentality.”
