Excellent article!
Now, not all registas play like 30yo Pirlo. He is the best I've ever seen at it but not the only interpreter of the role. Tonali is different but much more of a regista than a mezzala. He has the talent, stamina and age to play any role, but not optimally.
From Tonali himself now in the nazionale:
“This can also be my role. I am more of a Jorginho at club level, let’s say, but it’s not that different, so I have no real problems playing wider in a midfield three."
Put him under Sarri and I am sure we will see the new Jorginho, built in his own unique way.
I would have liked in that article to see him compared to the older Thiago Motta. He reminds me most of a mobile version of that Motta that evolved into a regista.
