I don't really understand the Roma 2007 comparison
Roma had a regista, David Pizarro, in between the two roaming midfielders. Pizarro dictated tempo, led the transition for counter-attacks, playing extremely deep in midfield to recover the ball from the central defenders in order to shuttle the ball outwards. Instead you have someone like Mascherano in his place? I don't understand that. Then you have Scholes and De Rossi in front of Mascherano, neither of them can replicate the role of a Perrotta in midfiel, a foil for someone like Totti to have even more influence in the final third.
Scholes does not run like Perrotta, even though he is more skilled. The runners weren't from wide, they were from the middle, which caused the main issues with the central defenders for the opposition. That's what the entire marvel was about with Totti, because it created space in the final third that you did not normally see with a traditional style of play. Scholes scored a lot when he was further forward, De Rossi had a couple of high-scoring seasons, but they're not real runners that shuttle for a regista, like Pizarro, who you have replaced with Mascherano. The entire concept doesn't work when arguably the most crucial position in the formation isn't played by the right footballer.
Di Livio doesn't provide the offensive threat that Panucci did when he was one of the top scorers for Roma that year. He's way more disciplined, Panucci played with much, much more freedom than he did in Madrid, that's for certain. Savicevic's not really a winger either, your wide players don't seem like the type to provide width...but if you mean that they would collect the balls from wide positions and come inside, it makes sense. Forgive me for not having read through all 6 pages
I mean, you do have a lot of similarities with that Roma team, even the weaknesses they had. I can't see many similarities between Mancini and Suárez for example, but it looks like Suárez has the same role that Vucinic had (and struggled massively with) after the ankle surgery. Savicevic is playing the Mancini "role" on the right which is where Taddei provided width, so I think you have it the other way around or something. You said early on that you're able to set the pace of the game and hold more possession, but that's not really how Spalletti looked to play, no?
It reminds me a bit like those movies that say "based on a real event" but it's just a small detail in the entire plot. Nice team though
