Stats can be misleading and I don't think anyone is arguing that Caldara is better than Bonucci at the moment. What I say is this:
Caldara:
- young
- has potential
- low salary
Bonucci:
- old
- unnecessary when we have Benatia
- high salary
- piece of shit for disrespecting the club
Besides, how exactly do you get that the numbers say Bonucci was better than Caldara? Same pass completion rate, Cladara has twice the number of successfull tackles, more interceptions, more aerial duels won, more blocks and more goals scored per 90m. The only thing Bonucci has over him is chances created. And the average rating on whoscored 6.76 for Bonucci and 6.95 for Caldara.
