Just look at their backline. In that department we lose hardcore.
If we assigned points depending on how good the players are...... the points from their defense would blow out of the water the points from ours. Bonucci alone would put us on a numerical disadvantage.
Also, i think that prime Kaka and prime Shevchenko were better than all our current players. Prime Vidal would beat prime gattuso IMO. And pogba would beat Ambro in quality. Llorente would lose against Inzaghi.
