Like a few people have said before, we're doing the mercato we should've done last year. We're building a decent / good squad without any real gaps, which should get us European football. Then the next year you're supposed to add true quality, top players, but only 1 or 2, as they would come expensive and go from there.
Personally, if we get a proper LW and a good CB, I think the mercato was fine as it was as a whole. Most stars were simply unrealistic and you can blame the board for giving us that hope. We have filled plenty of gaps and should now slowly start hoping and praying Conte manages to get us up there.
I'm not saying Marotta did a great job, as plenty of mistakes were made, but in the end.. I think we have ourselves a decent group of players.
