To be honest Pep never seemed to like Danilo that much, he was a quick replacement when Alves fell through and even when he was in really good form when Walker had his dip around Christmas, Pep never gave him a proper run in the side, he just kept playing Walker until he worked his way into form.
So if we're going from an attacking RB option Pep won't use to an attacking option he really likes for £10-15m I suppose that's a good squad upgrade. Plus he's younger.
I imagine this will mean more Bernardo RW. One of the few problems we have with him there is a lack of width because Walker isn't much of a threat in the opposition third.
If you're thinking about the 3-2 defensive structure the players have talked about in possession, you can have Zinchenko-Laporte-Stones at the back, KDB dropping back next to Fernandinho, Bernardo moving inside with Cancelo on the overlap, then LW and Silva on the other side.
