This rumour never made sense to me given how much Mourinho likes Valencia.
However iirc it was Mourinho that switched Azpilicueta to left back and he did end the season with Darmian in that position so he's not averse to inverted full backs. Maybe he sees him as the solution to our left back problems.
That RWB role is absolutely crucial to Mourinhos set up last season. Whenever Valencia wasn't playing we missed him a lot, and the problem is that Valencia can't play every game anymore. We need another option there that is able to offer the same threat going forward.
LB is actually less of an issue imo if we are going to continue the way we did last season. We have Blind, Rojo, Darmian, Shaw & Mitchell there. Our LB has far less onus on them to attack, so the first three can perform the job that Mourinho wants. Shaw & Mitchell being the more attacking opitons.
