This dude is so hard to rate... he's a beast in almost every aspect, anyway I think his DEF is too high. He's a good tackler, but commits so many fouls for bad timing. Kinda like Vidal. Of course, you could say Vidal has higher RES and that makes him a better tackler in game, but also that's because he's like a dog hunting players, like Medel. Verratti is more conservatory (does that word even exists? Who knows), his tackling overall is very good (in fact if you check any video of his highlights you'll find tons of really good tackles that make him look like he deserves 80 DEF or something), but again, he commits so many fouls. Also he's at 83 BB (probably could be at 81, anyway I think the value doesn't overpowers him, he's quite strong while on the ball and also without it, when he's trying to recover it, he usually shows decent strength), and that helps him while defending. I think he should be at 76 DEF. With the current RES and BB level he has, he would still be good in defense, but not that good as he is now.
Now about his ATT: this has been discused before and I think most of us think that he should be downgraded. I mean, he's 8 points above Busquets. And I recognize Verratti is superior in this aspect because the role he plays in, he plays much more incisive passes that Busquets near the box, while Busquets usually is closer to his own box. I really won't give Verratti more than 76 ATT, he's more dangerous than Kroos, for example, but 78 ATT combined with his SPA/LPA (which are fairly rated btw) makes him a freaking good playmaker, with he isn't.
Also I was thinking in lower DS, he isn't fast at all with the ball. He's pretty good with it at his feet, but his movements are quite slow. It's almost impossible to steal the ball from him, but that's thanks to his DA and BB, no because of his DS, which could be much lower in my opinion. Same for TS, could easily be in whites.
He needs Sombrero Card btw.https://www.youtube.com/watch?v=UODLeWs-E7Y
