Not even one goal per game is unacceptable, especially if you consider that two of them came from penalties and most of the rest came from flashes of brilliance rather than team play. Our front three just isn't clicking and it's not gonna miracolously change as they play together for quite some time now. Hakan and Suso are not productive enough and until we change them for quicker, more skillfull players, capable of scoring and assisting consistently, nothing will change.
Yes, there are many other problems in this team, but I believe we should start fixing them with complete revamp in our attack. Defence is ok for our current goals, maybe just sell Calabria and bring Celik for the same money. Conti showed promise last game and have a higher ceiling than Calabria if he finds consistency. Midfield should be fine too after we exchange Kessie for one of Xhaka/Torreira. Last two games showed that we are capable of playing on par with Lazio and even Juve. It's lack of goals what's hurting us. I would even say that impotence of our attack is bigger problem than lack of experience/leadership. It's not like our players were scared of Juve or something, we just don't have players with goalscoring instinct and when our striker is out of form there's no one able to do something special.
I would still absolutely love to see Milanista Belotti in our jersey. If he's available for the same money for which we could sell Piatek to ManU/whoever is willing to pay, I would do it in a heartbeat. Then buy goalscoring left winger instead of Hakan and tireless runner instead of Suso and hire top coach playing 433.
Donna - Theo, Roma, Caldara, Celik - Paqueta, Torreira, Bennacer - Depay, Belotti, Chiesa.
If needed, use Hakan's workrate on the wing or in the midfield without pressure on him that he has to score, play Krunić if Bennacer needs time to adapt to playing RCM, let Belotti teach Leao how to move and work hard for the team...
It's doable in two transfer windows for approx 110m (Depay 40, Chiesa 70... Calabria <-> Celik, Kessie <-> Torreira, Piatek <-> Gallo swaps, if we have to pay something extra, Suso's sell should cover that).
It's also much more "Elliott way" than bringing 30+ players like Thiago Silva, Modrić, Ibra on massive wages... Potentially top 3 team in Italy for next 5 years.
This winter, we should just send Calabria to Sevilla and bring in Celik, swap Kessie for one of Arsenal's unwanted duo and bring Ibra for six months. Then secure top coach and let him to chose his attack for next season.
