Top post as usual MO, I agree.
Zinchenko is a top class player IMO, huge leader too as you said and a player with a great mentality, a will to win. What he adds to this team is unique, the inverted full back role he plays, regularly sees him in Midfield linking play with Partey, Xhaka and Ode. Zinchenko is world class on the ball, rarely gives it away, beats the press with ease and he is a great dribbler. He is a top top player, in the kind of mould of someone like Philip Lahm or Joshua Kimmich.
