Hasn't Juventus always had role player mids in the past? We've had players like Tacchinardi, Blasi, Giannichedda, Matuidi, Khedira, et cetera. Even going back to Jugovic. Typically Juventus have had at least one player to fight for the ball or press, whether it be as a DM or box to box mid, even though they might not be the best with the ball or have a stunning passing range. We'd field one of these types of players more so than not.
Seeing as though we have no other players to fulfil that role, I'm not really sure what all the complaining is about, unless folks just don't believe in pressing anymore. Or if you think Mckennie isn't good enough for that type of role, suggest someone who's better and can be purchased. And no, not Vidal.
