He was a great CB but i don't think he was ever the best CB around, and I don't think you can say he was ever better than Varane. Nor faster! But for pace maybe I just didn't pay enough attention to him, but I'll blame him for that by not playing in one of the biggest leagues.
I'll maintain that you simply can't judge his level accurately as a CB when he played against lesser opponents for most of his career, instead of going to La Liga or the Prem. The only way to show your quality in the Bundesliga, Ligue 1 or Serie A over the past decade (for the most part, Bundesliga and Serie A have had some good years but mostly been dominated by 1 team, while Ligue 1 is just a much weaker league), is to show you are the best in the CL. And between 12/13 and 19/20 while Thiago Silva was at PSG, they just leaked goals in the CL knockout rounds and their eliminations...
- 12/13 - 3 goals to Barca, quarters
- 13/14 - 3 goals to Chelsea, quarters
- 14/15 - 5 goals to Barca, quarters
- 15/16 - 3 goals to City, quarters
- 16/17 - 6 goals to Barca (6-1 hammering), Ro16
- 17/18 - 5 goals to Madrid, Ro16
- 18/19 - 3 goals to Oles United, Ro16
- 19/20 - 1-0 loss to Bayern in the final
Or with Milan in the 3 previous years, conceding 7 to United in 09/10, losing to Spurs in the Ro16, and then another 3 goals conceded to Barca in the quarters.
Basically, the only way to truly judge a CB for me, is how they've done against the elite sides over the years. Thiago Silva has simply not done well with his teams before Chelsea. Not all his fault of course,
but how else can you judge him? By performances against Lyon, Troyes, Rennes? It's the issue that happens when elite players go to PSG. Their league play is irrelevant and you can only judge what they do in continental or international football. And while yes Thiago Silva is still a great CB, I just don't think he's ever shown something to be ahead of Varane, Ramos, Pique, Rio, Vidić, etc.
