1) a double pivot is a non starter we don't have the players for it, asking Pedri to play in a double pivot where he sits and De jong drives shows a lack of understanding of his abilities & the system itself, to be Frank Pedri doesn't have a place in a double pivot system, unless he maybe goes back to being a winger, he can play AM doesn't offer enough of a treat for that position & can't play in the pivot.
So having established that its literally a bad idea to even entertain the pivot with him in it, we have to figure out better ways for the team to be able to adjust when teams press us, because that's what everyone will do now.
1) drop busquets
2) in the very likely event he isn't dropped, out midfield as to become more compact,to give busquets more passing options.
3) if two isn't the way koeman wants to go, he prefers to have his midfield stretch into some weird 1-1-1, then our fullbacks have to come inside like pep does with city to provide more passing options when we are pressed.
4) we need a bit if pace up front, I have personally lost all faith in dembele,but he is the only player we have that can run,when we get him & fati back and koeman chooses either option 2) more compact midfield or 3) fullbacks that tuck in, we should be able to manage the press better.
