No handball cause it came off his body/leg first. At least that was my impression watching it live.
2nd PK i thought was pretty clear. Happened right in front of me. On camera, looked a lot softer than it did watching it straight on from behind the goal. To me, looked like Kessler body checked him pretty hard in the back and made zero attempt for the ball. hence the PK. if they had collided while both going up for the header, i would have had no problem with that. taty jumped, kessler didn't. there's an angle from behind the goal in the highlights.
Bou looked offsides to me too but guess not enough to be overturned with our weird YS stadium camera angles.
