So, basically he’s the same player he was at City? This is exactly what I heard about City fans speak about him.There's been light and shadow.
On his day he is a phenomenal player, can dribble past any opponent and his shooting technique is top notch. But he only showed glimpses of these abilities at Bayern.
He clearly tries, but I think he still has a lot to learn in order to succeed in this Bayern team. He competes with Coman, Gnabry and Douglas Costa for playing time. Coman and Gnabry are clearly ahead of him in the pecking order. Even though Gnabry had a very quiet Hinrunde, Flick seems to trust him more than Sané. Coman did very well, Douglas Costa basically is a no-show.
Sané tends to make wrong decisions. Often he dribbles too much, when passing is the better option. Generally speaking, his decision-making is lacking an understanding of Bayern's way to play.
When Bayern cannot counter, they have to be patient and shift the ball from left to right and back again in order to spot the moment when their opponent isn't organized enough and there are gaps in the defense. Often Sané tries to solve these situations by taking on an opponents. Sometimes this is appropriate, sometimes he's just not patient enough. As Bayern defend with a very high line him losing the ball when dribbling is quite dangerous and something they want to avoid.
In addition to that I also remember him sulking from time to time, being "angry"(for lack of better word) with his team mates, when they misplaced a pass.
He also has to improve his back tracking, because when being compared to Coman or Gnabry, he looks lazy.
Today Bayern played Hertha and Sané started the match. He had some really good situations, where he set up chances or dribbled past players, he also sometimes chased back and helped defending when there was a change in possession. These were very good actions, however they were tainted by some really unnecessary losses of possesion. I think this sums up his time at Bayern quite nicely.
All in all I think we still have to wait for 6-12 months in order to reach a clear verdict on him. He was injured for a long time and already missed a month this season due to an injury. I still think Bayern took a (certainly well calculated) risk when signing him.
In Twitter today I saw a video with Pep giving insight on Cancelo role and position in the team and he said what he expects from his players is to do the simple things and not complicate an action, key thing he said, “Great players are not great because they do exceptional things, but because they do the simple things well.”
This very much down Sane alley he doesn’t seem to do much of the simple things right and always complicate specific actions, which is why he lost his spot at City and hasn’t cemented a spot in Bayern yet but he’s still young so there is time.
