I read the other review regarding Sane and it was so negative that I felt like I had to write my first review for a player to do him justice (I even created an account for this).
For me Sane has been phenomenal. I play him as left striker with Gareth Bale being the other striker and Marco Reus Bundesliga POTM being the CAM and let me tell you, he is by far the best out of those 3 regarding striker qualities.
He is lightning fast (feels way faster than Bale) with very high dribbling, agility and ball control. With a Chem Style that boosts his shooting (I used Deadeye, as his pace doesn't need a boost, and to boost his shooting and passing is the most important for his role as a striker).
His positioning is exceptional (99 with a Deadeye), he always gets in behind the defenders and when you play a good pass, there is no catching him even with the fastest defenders.
His shooting, especially in the box, is breathtaking. When he gets sent in the box and finishes with his left foot across goal (98 finishing and 98 shot power with a Deadeye), he always slams it top bins and even his 3 star weak foot feels more like a 4 star weak foot. His shooting from outside the box is great as well, his timed long shots and finesse shots go in most of the time (84 long shots and 89 curve with a Deadeye).
Furthermore he is quite tall, so that he scores a lot of headers too and doesn't get bullied off the ball easily.
Last but not least, his passing is also phenomenal. With a Deadeye, his vision goes up to 94, his crossing to 90 and his short passes to 91, exceptional stats for a striker.
All in all, Sane is my favourite player in my squad, with by far the best goal to game ratio.
Pace (oh boy he is one fast player)
The combination of positioning, finishing and shot power, which makes him score every chance he gets
Passing (with the right Chem Style, exceptional for a striker)
His height (makes up for his "only" 72 strength, feels like 80+ strength and great for headers)
Dribbling (which feels even higher than it already is, even without boosting it)
His 3 star weak foot, although it feels more like a 4 star weak foot
