Torreira is 100% getting a +1 so I'd bank on his, also imminent transfer to Arsenal looking so that'd be my bet.
For RB I'd say pick up Odriozola or Montoya 87 and 88 respectively and due to get a +1 each. For LB check out Masina, 87 with a good chance of +1
For CB I'd advise you to pick up Ferrari or Hateboer. Hope this helps
