Not wanting to go all Zatara about it (soz mate), but I don't think we do need any more senior players. We already have: Pickford, Young, Coleman, Tarkowski, Gana, Danjuma, Doucoure, Iwobi and DCL who will likely play regularly who are senior pros.
We don't need experience for the wings, as that will likely increase cost of our targets, or diminish talent. A senior CB will likely block Branthwaite. Seeing as we are unlikely to see the back of Godders or Keane, a young, talented CB would be a nice addition there for if Branthwaite is out of form. Don't think we'll be signing any midfielders without sales.
Which leaves upfront. Now, in an ideal world, you would want a proven goalscorer - but they cost money we don't have, which then leaves us scratching around the Che Adams of the world, who is proven crap. So (even though I doubt we are in for him), an Ekitike (I.e. someone with a few more years of senior football than Chermiti) is a much better option for us right now than the former.
Ideally, I wouldn't like any more 'senior pros' coming in at this point!
