You may play to a decent enough level but that doesn’t mean you understand the game as well as you’d think. Look at how many pundits who played at a far far higher level than you can chat absolute shit. Two assists is quite low, but he isn’t a player who assists. Let’s used Scholes, he was averaging around 4 assists a season when he dropped further back into midfield. But by your metric he was good but not top quality. It’s not that Thiago just recycles the ball well, he controls the pace of the game, he’s great in tight spaces, he passes forward almost every opportunity he can and his range of passing is excellent. Defensively he does a lot more work than you’d think with the most tackles and interceptions per game. Honestly if you don't think he’s a top quality player then maybe don’t think about coaching when you hang up your boots.
