If there's any chance, and especially if we can get a decent fee for Gusto, Livramento should be brought home as a priority. He would be excellent cover either side at fullback James/Cucurella/Hato/Livramento/Acheampong is a very good quintet for a season, even with injury.
Gordon at his best is a very mediocre player similar to Neto, a player whose game seems to rely entirely on running around until the opposition makes a mistake. It comes off every now and then, but 30 games a season it is beyond useless. Tonali is Fernandez with a different set of problems, he lacks any sort of output but he is a great facilitator. Similar to Mateo Kovacic, he could either be the missing 'glue' in the right midfield or he could just make a lack of creativity/attacking output worse. I doubt Newcastle would let Guimaraes go to a PL team, but he would undoubtedly be a fantastic signing who despite being a DM would complement Caicedo really well and allow the team to play a genuine 4-2-3-1 pivot again, similar to Matic/Kante with Conte.
