His SPA was lowered because with 81 he made just too many good (and great) passes to the wingers and all, but in reality he fucks it like 80-90% of passes. If you analyze him, you will see he mostly does as a pivot, he trap the ball really well and maintain the possession and normally he passes to the side, thats his style, thinking in that he shouldn't deserve yellow SPA, almost always he tries forward direct passes he gives it bad, too strong so his teammates can't catch them or too weak so the pass is intercepted, or simply plain awful pass.
About SA, its probably one of his weakest attributes really, just how many goals with his foot have you seen? now, of those goals, how many of them have good accuracy? then again, if you analyze him, you'll see he scores mostly headers and first touch goals, when he scores with his shots, is because he puts mostly power rather than accuracy. I may be wrong and i could have been a little harsh with him, but it works really well in game. he is a monster in the air and can anticipate defenders effectively, but his shots are awful (just like reality, when i remember how many games we could have won if he was a better finisher...). That's my view, it's up to the debate.
completely agree about TS btw
