Trying to understand why City are linked with so many playmaking midfielders when it's Fernandinho they're trying to phase out. Swapping out Fernandinho for Jorginho (before we bought him) or Pjanic/Kovacic doesn't make sense to me. We've seen what happens when Stones and Otamendi are left exposed and it ain't pretty. So why replace your only defensive minded midfielder with one who isn't?
Because a Cdm cum Playmaker dictates the game from the back with the ball and can pick those attacking passes to the forwards running in behind the defense with ease thus increasing attacking Ruthlessness and creativity on the ball. If you notice Fernandinho too has got very good passing range and picks those passes from time to time. So it makes it very difficult for the opposition to press so high on the player dictating the game from Cdm thus the team circulates and keeps the ball way better with playmakers all round the midfield.
While when they loose the ball the attacking midfielders and forwards collectively press the ball along with the Cdm which reduces the transition speed and stifles creativity of the opposition teams so the Cdm alone does not have the duties to break up the play as they do it collectively by closing the ball and space down as quickly as they can and Cdm 's passing range immediately can turn defense into attack after winning the ball back.
Thus when you have so much of the ball a player who can dictate the game and pick passes adds another dimension to the attacking football.
If they loose a goal or two they don't mind as they believe they could outscore the opposition and keep the ball from the opposition for majority of the game.
