It's definitely a problem and its impossible to know the reason(s) without having full knowledge what's going on behind the scenes and at the training pitch. One thing I assume Pep has said to him is that he needs to learn to take his time in the box. Not hit it first time if he has time and space to take another touch, remain cool and use all the time hes got. He doesn't really have the shooting power nor the technique to hit it while in motion (in the box) so he has to focus on placement which is much easier if youre not at full speed or rushing the shot.
This works really fine when he's confident because he hits it first time when he should and manages to get a shot away even when taking his time. The problem is when he's on a draught or like the miss he had against Lyon (when hitting it first time). I imagine that troubled him a lot and he's scared for something similar to happen again. He's very reluctant to shoot in the box unless he has everything under control which in the end leads to him overdoing (looking for the perfect shooting opportunity) things and ends up with him looking silly. He's showed great mental strength before and has always started the new season on fire. With Covid prolonging the season and us being eliminated from CL in the middle of August meant he barely had a break to rest and clear his thoughts from the Lyon game. I still don't think he's over that miss and he might need a huge moment (for him) this season or a long break to actually recover from it.
All this are just my speculations and I might be very wrong but that's what I'm seeing right now. He's on 6+4 so far in the league which isn't terrible in any way and he's scored some decisive goals for us already this season.
