What is this rubbish about Thiago not being world class? He's almost undisputably a top 5 mid in the world on form and I can only implore you to watch the games if you disagree. I've followed Koke since he first broke out at Atleti and he hasn't been on the same level for years, and Thiago is better than Iniesta and probably Silva too. The main reason he lacks the caps that Koke has for Spain is because of injury.
The recency bias is absurd due to his injury and not having really played this season. He was integrating into Heynckes' system quite nicely and has been arguably Bayern's best player in up to 2 of the last 3 seasons which MANY Bayern fans would agree. He was pretty much Ancelotti's most important player in what is/was an aging squad. Coutinho is obviously having the better season but you could say he's been doing better than the likes of Kroos, Isco, and even Modric right now too. Doesn't reduce the class of those 3 at all because we all know what they can do on their best game.
Thiago is world class and has been for some seasons now. If you're holding CL success against him then I guess a lot of the Bayern players haven't been world class since 2014, Verratti isn't world class, hell Coutinho too hasn't 'proven' to be world class yet either. Thiago's done fine and produced big games vs the likes of Arsenal and Juventus, regularly wrecks Dortmund too domestically even when they were a stronger team. He did pretty well against us in the return game in 2015 too.
