The big difference is Zinchenko has played his entire career to date in midfield at UFA and for the national team at every level, with the exclusion of last season. He’s already shown the intelligence, adaptability and technical ability as a left back to prove he can play in midfield for us.
I’m not saying for one minute he starts in front of Rodri, Fernandinho, De Bruyne, Bernardo, Silva, Gundogan or even Foden because he doesn’t but if we need him in there he absolutely can and will do a very good job. We play that many games and with doubts surrounding the fitness of 3 of the above names he’ll get a chance at some stage and he’ll no doubt take it.
With Silva, Gundogan and possibly Fernandinho (I maybe wrong on the last one) all potentially leaving at the end of the 19/20 season then we’ll need Zinchenko, he’s a perfect player to have in any squad.
