We'd have a pretty slow attack if we go in with Sancho, Bruno, RW with mediocre pace and Ronaldo into next season.
I sort of agree with the rest of your points but I think we primarily need a ball carrier who can cause some chaos and beat his man. Many ways to go about it, Bernardo, Salah, Hazard are all totally different players but leave them 1v1 or 2v2 (with fullback support) and they will make something happen from the half space.
What I definitely don't want is a young Mata type player. We already have Sancho on the left for that.
I do think the position is a priority. We can stumble along defensively with Shaw / Telles, Lindelof, Varane, Dalot / AwB for now.
DM, RW, CF to rotate with Ronaldo are my priorities.
