we should get some fullbacks, that's not even up for debate.
but look at our midfield next year: locatelli, rovella, miretti and fagioli are most likely to be here, pogba too (but i bet he won't be available for more than 30% of the season). and that's it. rabiot's contract expires and he'll get better offers, mckennie will be sold and he's not a starter level player anyway, paredes won't be purchased, arthur and zakaria won't never play for juve again. so that's locatelli, rovella, miretti, fagioli, and a crippled pogba. that's fucking thin.
until someone comes up with better ideas i'd say sergej should be a priority. not THE priority, just ONE important player to keep an eye on. i don't expect lotito to be easy to deal with, and we should most certainly not overpay (anything above 40m would mean that), but if we can get him, we absolutely should.
