But when, and in what situation? Last year is its own situation. We can discuss that at length elsewhere. THIS year, with the exception of pre-season and the Limassol match, Roberto has generally not been playing at the same time as our best midfield. Of the extensive list of names you provide, we have 4 fullbacks, 2 guys no longer with the team (Holtby and Siggy), 2 players who have shown they are not big chance creators (Paulinho and Dembele), 2 wingers who are either in sharp decline, or have yet to show an ability to pass to anything other than row Z, a 19-year old, a striker and 3 guys who, as I just mentioned, also were not featuring much last year, but are catching fire this year.
You can arbitrarily write a player off if you like, but your list is comprised of mostly players who don't create scoring chances, and 3 guys who do, but who Soldado has yet to play with extensively. If you don't like a person, fine, but just say that rather than claim he was playing in a system catering to him when he wasn't.
