Heung Min-Son will be a great signing. Can play all across the front 3 and even in the 10 too. And will provide excellent mentoring for his countryman Yang. You can see why we’re after him.
That's the only justification for O'Nien I can see, if he is being eyed as someone who can come on for Grimes to see out games and manage his minutes, while also being able to play CB.
I don't get the concerns about squad spaces. We have a small squad. Who's taking them up? We could easily cut the likes of Bell, Andrews, one of Bidwell/Brau if we need to make spaces.
