Bayern are so easy to defend against let the wide men have it don’t need to worry about them going on the outside as they always come inside or pass it backwards - perfect for them to get hit on the counter by Celtic too as they commit so men forward just to kill all the space and do nothing with it.
Kasper didn't help him by where his save put the ball. First rule of keeping, if you cannot grab the ball, make sure you parry it out wide and not straight forward, so the angle is narrower to score from.
