Regardless of jack's future villa is where he was developed - Players over the years have been the next big thing Moore brothers, delfonseo etc etc. But, jack is a truly world class player in the making with a unique style to his game.
I'm very happy he is a villan and clubs are jealous - Mount, Maddison and other midfielders they are typical English midfielders. Grealish as his own style and totally owning it.
