I prefer that number being carried by a worthy player like buff, instead of being speculating on who will get it, and players getting uneeded responsability, comparisons and bashing for wearing it.
In another team i would not care much about it, but in a juventus team which just lost their most emblematic 10, i think is an unneeded issue. Give it to gigi until he retires and forget about this "10" drama for a couple years.
