They are upgrades for Roma though.
I don't rate Digne at all. Sure, he might come good, but I don't really see it. But, again, an upgrade over the shit they have at left back last season with Holebas and Torosidis splitting time there.
Rudiger is an interesting case, as he is quite promising. If he puts the injury setbacks and poor form of last season behind him, I could see him displacing Manolas (assuming Castan gets back to his best) as a starting CB. Manolas was positionally terrible last season. Tough, pacy, and decent 1v1 defending, but he was caught out of position a ridiculous number of times.
