Playing "attractive" football, the way most people most of us would describe it starts from the back. Fullbacks are very important in this. With our current fullbacks, this was a very difficult task, considering Cuadrado has been integrated as one late in the season and A.Sandro's form. Then, having Matuidi and Khedira in midfield doesn't help either. With Cuadrado as our main RB next season, and hopefully A.Sandro on the other side, and by replacing the holes in midfield, I am sure Allegri will be able to play more dominantly. Costa has been introduced slowly and wouldn't be for his injury, Bernardeschi would have been a starter in the second half of the season too. With these two fully integrated into our play, I am sure we will be able to play the football most of you guys would describe as attractive. The key is that we shouldn't sell either Dybala or Higuain (who despite criticism will deliver even more with a more dominant play)
I honestly get very annoyed by the criticism Allegri is getting for his type of play. The roster has been dismantled over the years and replaced by inferior players who don't fit in the system previously used. He needs to match the pieces, and he is somehow able to do so every single year. There is no coach on earth who could have achieved what he did the past four years and, wouldn't have been for our horrible home game and the referee, the changes were that he would have been in yet another CL final. With the current limitations of the squad and players starting that really shouldn't be close to a starting spot at his disposal, this would have been somewhat a small miracle. This year honestly has been a very strange year, with players in and out of form, players seemingly past their primes and I don't think you can blame Allegri on much of the roster selection. Let's be incredibly happy with what we performed this season, winning yet another double. Let the man do his job once more, and see whether this summer Marotta and co will deliver and give him the squad he deserves to fully challenge for the CL. If there is any proven coach out there who would be able to lift the trophy with this squad, it would be Allegri.
