Eriksen should be the priority signing in my opinion, along with Arthur, who must be brought in in the summer already. The perfect Iniesta replacement, and a Xavi-esque player, who wouldn't cost much, but can become really good for us in finally fixing the midfield controller position. Both together could return our midfield to a place where Messi doesn't need to drop back every match, because we wouldn't get a quality pass to the final third of the pitch otherwise. It would be nice to get both Eriksen and Griezmann of course, but for that we'd need to sell out all the trash, including players who are doing okay, but can't add anything more to the team than a La Masia graduate could, on a much lower wages at that too. The prime example being Paulinho, Digne and Paco, if we promoted Alena, Cucu and Arnaiz. Add to that the real trash that should be sold no matter what (Gomes, Vidal, Rafinha, Denis?) and we would get more than enough from all those sales to buy Eriksen as well, since Griezmann seems to be the priority signing. But that's sadly a much too advanced thinking for this Board, i'm afraid.
