Sorry, just seeing this now.
Are you honestly comparing Thiago Silva, one of the greatest CBs of the modern era, to Mike Smalling? Lol. Say what you like about the age, the salary disruption etc. but he's a quality player. No different to Untied signing Cavani, Zlatan, Laarson etc. just at the other end.
He's 36 years old and he controlled Rashford in multiple isolated situations; situations where he has ended Demichelis & co. in the past. Also produced an absolutely world class block against Cavani that doesn't get as appreciated by people who weren't defenders. He led the line, extremely efficient on the ball, and so on.
If you don't have much weight for my evaluation, let stats and a fellow CB tell you:

Interesting you though Zouma was good. Thought he looked extremely uncomfortable, especially underselling the switch a couple of times. Thought we should've took more advantage by pressing him like we did Cahill a couple years back under José.
Guess we see the game very differently. But wonder what your opinion would be if that was a player in red i.e. Bailly or Tuanzebe
