Look, no matter what your agenda/opinion is, just use the data right. That tweet doesn't prove who was the best defender for us. It's kinda a random stat for a defender, anyway.
And to be clear, I do feel that Bastoni is a special player in his position, while Skriniar is "just" a tough CB with grinta.
But let's not be angry at players - just because Skriniar left because he didn't feel valued enough (you can blame the management, same happened with Perišić) and we are a club that is constantly on financial edge, I can't really blame him - why commit to a club that does that? The management owes us a Scudetto just for paying Lukaku too much last season.
If you got attached to Skriniar because he was a sweet talker, newsflash, all football players (unless if your name is Osvaldo) are sweet talkers. C'mon now.
