I already said he deserves an update. He isn't a good finisher, he's so close to Lucas, what isn't true. I see him about 67/68 on SA and ST. SP also would be fine at 84-85. He's also faster and quicker, though he does not seems to be. His speed is deceptive, his long legs allows him to do large steps. He's easily bordering a 80 for TS and 78-79 for ACC. With the increase on TS/ACC ratio, I would also decrease his BB to 86, though I do think he's REALLY strong. The way he push way his opponents is impressive, but as a 187/75 guy, he doesn't need a so high value. He's also a better short passer than Lucas (who I see a bit over on passing skills), but he's more conservative. He keeps simple passes, while Lucas is more audacious. I would say Lucas SPS is probably better than Sandro, but Sandro SPA should be one point higher. I'm more inclined to give Lucas a SPA 80/SPS 82 and keeping Sandro as it is on first post. His LPA is well rated for now IMO, but his LPS should be simple higher, easily a 80. He generally puts a decent power on his long passes, and I already have seen him doing some amazing long passes from the defence to the attack.
Also his Header and Jump are overrated. His Header shouldn't be over 79: he isn't really a better header than Lucas, and I think Pato is way better than him when it comes to putting strength and direction on the ball with the head. Jump could be a 80, he isn't something impressive there. He mostly relies on his body strength to win aerial duels.
Technique shouldn't be under Lucas, IMO. At least on pair. His first touch is sweet and smooth, IMO a softer trapping of the ball than Lucas.
And for last, but not least: would increase his TW to 83, one point over Lucas. He's so vocal, a leader on the midfield, dotted with calm and always doing the correct decisions.
