Garnacho is talented player, a ball carrier (which you can tell from his progressive ball stats), has great off ball movement and position (on eye test, you can see that he always in the right position in dangerous area to score/assist), and his quality delivery is good but his poor decision making what makes his delivery looks bad. For his weak points, he doesn’t have closed control dribbling ability, physically still weak (this can improve), and has clumsiness in retaining possession (he tends to give the ball away cheaply). He is a winger who cannot play as wingback and we are playing no 10 and wingback formation with no wingers. Although, he’s still young and can still develop to be L10 but it will take time with no guarantee he can develop into L10 for us. Overall, he has great assets but also weak points, which I think the club should be open to sell him if the good price comes.
We should only sell him in January if selling him actually allows us to sign a regular striker and a regular midfielder in January. Gyokeres & may be Ederson. Apart from wingback, our no 9 spot and box to box midfielder spot are also our weak points at the moment.
