I'm kind of more relaxed in terms of another striker signing now we have Zaniolo (yes I know he's mainly a CF/No.10, but I think he'll do a job IF Ollie goes down with a short term injury).
I'm also fully trusting UE's judgment.
That said, I'm still baffled as to why we've not done anything at RB, especially with Young leaving.
The only thing I can assume is that we're planning to play with Cash as an inverted wing back/RM as per Burnley on a more regular basis. I don't think defensively we're great shakes down the right, and if Cash gets injured we could be in real trouble, shoehorning CBs and midfielders into that spot. Fullbacks are amongst the most specialised and key positions in the team these days.
