Maybe
You're wrong, no?
Saliba getting destroyed on this forum for some performances where his passing was a bit off or he didn't clear the ball properly and forum experts will say how Deschamp is right about not playing him and then you see this video but no sign of forum experts to explain it.Konate is a good player. He has had his fair share of bad games last season. Particularly remember Brentford away where he had a complete nightmare. This season he has been very good (apart from when he comes up against Havertz). Don't know why you think people have bad opinion about him as most people seem to rate him on here, even if obviously they don't rate him as high as Saliba.
As for Upamecano, you must not have seen him play a lot if you are surprised why people don't rate him. For an 'elite' defender he regularly puts in comically bad performances. I would probably take Holding back then take Upamecano, he is that bad.
