Based on players I've seen, except Maradona (only his last years).
I would play 442 in diamond because it is my favorite system. I want to have a 10 and a pivot / constructor / destroyer.
In the defense I wanted to include offensive full backs, such as Alves and R. Carlos, as well as Ramos, for his character, for appearing when necessary, for the ease of starting the clean play, and also for having someone a little dirty.
The problem with including Ramos and Roberto Carlos is that you need someone to correct their distractions and to be a pure defense, a "Cannavaro", but I still couldn't find the solution, so I stayed with Maldini (which I have copied from other posters). Very solid and perfect if I go crazy with Roberto Carlos in the middle.
For midfield I need someone to steal the ball, but that is not enough . The play would not start as smoothly. It has to be destructive and good with the ball. Matthaus is a good option but I didn't see him play or if I saw him I don't remember.
Xabi Alonso sounds good, as well as Busquets, but I stay with Redondo, out of sentimentality.
I imagine a 2020 match, with this intensity and I don't see Zidane or Iniesta resisting. I think the midfield would collapse. I do not know if I need so many "similar" profiles if I have Maradona . So I am going to stay with Modric, who I think has a lot of characteristics, resistance and good defensive work (at least 2 or 3 years ago). The other position was difficult to decide. I may be too defensive , but I would play Davids. Stamina, going up and down and able to totally free Maradona , while not constantly expose Redondo and the full backs.
For the attack I would like a fast forward, good against the goalkeeper, and Ronaldo Nazario is a great option.
For the other position I would like a good header, small area forward. I think Cristiano meets all the conditions.
