An honest question, what build up? A huge hit to us making 1,000 passes around our box at 2 miles per hour until someone commits a bozo and it costs us? Ederson's best moments in recent times have been his long passes, especially to Holland. This so-called build up from the back hasn't produced fruit in quite some time. How about we keep it honest...
By build up when the keeper has the ball I mean this.
We are a ball control side as are most of the top sides in world football now - Pep has revolutionized play in this regard.
So what does ball control mean when the keeper has the ball and we want to build from the back?
Most often, it means that there is some pressure, but given the ability of the keeper, the back line and midfield on the ball, it makes sense to build from the back - the keeper most often passes to one of the back line players and from there the play builds.
In contrast to this, is playing the ball long. Here the keeper hoofs it forwards. In the case of our side, this occurs when the keeper notices that one of our forwards is breaking into space. But it also occurs when the press is so aggressive that playing from the keeper to someone in the backfield/midfield is too dangerous given the opposition press.
Donnarumma doesn't fit our system because we're built on ball control and have relied on a keeper who is excellent on the ball to form an 11th man when building from the back. Our backfield contains several players who are not good under pressure and are not great at passing. In this situation Ederson or another keeper who is great on the ball is essential to compensate. We can still mostly build from the back if our keeper is excellent on the ball in spite of shortcomings in our backfield.
With Donnarumma though - we have a keeper who is worse on the ball than every single one of our backfield players to the extent that it's a last resort to play it back to Donnarumma if we're trying to build from the back.
Which either means that we play from the back as we always have with much more frequent mishaps, or we play it long - leading to much, much less ball control - a long pass forward to a non-breaking Haaland or other player is probably a 50-50 proposition and we'll lose control of the ball much more often that we did in the past.
