At the moment I think we are in a really weird place.
The 433 we have used in preseason looks great. Silva aguero Sterling up front will wreak havoc, and the 3 man midfield negates Yaya's defensive liabilities. Having Delph and Fernandinho next to him will be a very effective midfield, even if Delph is not the star player that pogba is. Fernando also looks like the player we were supposed to be getting in this formation as well.
However if we buy De Bruyne, great player that he definitely is, I can't see how it doesn't unbalance the squad.
To accommodate everyone we have to switch back to 4231 with Yaya and Fernandinho in midfield once again and all of the defensive frailties that cost us last year reemerge.
Some people are suggesting silva play in midfield in the 433 but that doesn't change anything, he isn't going to drastically change his game and start providing cover for Yaya when he goes forward in the way that we've seen The third midfielder do so far in preseason. That selection is still effectively a 4231.
I absolutely love De Bruyne, but his signing makes no sense unless we also sign a central midfield player, like Pogba, who we could get away with playing in a midfield 2 next to Fernandinho.
