I agree with you that he was doing well, especially against Traore, but that lack of conviction in the challenge is what he will be remembered for today. However, I do not blame him at all for that goal. I am pretty sure he was on a yellow card already and had to be careful not to foul otherwise he'd have probably been sent off.
For me, there were two others that were more responsible for that goal - Luiz for not taking Traore out on the wing and, Konsa for not being closer to Jimenez when he got his shot away.
