He can produce an insane individual magic from time to time like a few times this season.
But Barca's Cm will touch the ball 30 to 100 times per match.
In those regular actions, when we slowly build the game, he always seems like playing too safe.
Those things can slighty improve with playing time, but I see his midfield game as: too safe pass, too safe pass, nothing, too safe pass, a crazy run suddenly.
Instead of: a constant attacking pressure and some sort of risk in almost every action (Xavi or Busi style).
He is still an awesome squad player for a cdm, cm and a rb. But him as a starting cm, imo, we would lack a lot of classic Barca-midfield things over 90 minutes.
Imo, Raki, Arda and Rafinha are offering more in that midfield part in terms of constant threat, constant courage and creativity over 90 minutes.
But Bob offers more running and some random, isolated crazy solo runs like from yesterday.
