I wonder if the club have accepted that the hole I pointed to that we have is a top quality DM.We push quite far over in several phases of play. We play two wingers who are not always (I'm assuming by design) tracking all the way back. It's quite common for our ball side CB to get quite wide. The other one pretty much has to follow unless one of the midfielders drops in.
On stepping out. There were also situations where Romero stepped out and that helped us win the ball. Those situations are rarely scrutinised, because we win the ball. But the one's where he steps out and doesn't win it often get a lot of attention.
Actually analysing if him stepping out as much as he does is helpful to us or not is much more complex than just looking at the times when it doesn't work.
I'm assuming if Ange thought it was a frequent mistake he would ask Romero to change. As Romero has shown very much that he's capable of in several areas (playing back three vs back four, playing with rapid VdV or slow as a brick Otamendi, less aggression and yellow cards).
Seemingly Ange isn't asking him to change, he's even putting him back in quickly after injury, showing no signs of rotating Romero out in the league as quite a few here have wanted.
As you said, if you had someone with the positional and situational awareness of a Rodri, Rice etc, anticipating when Romero is going to come out aggressively and stepping into that gap you would compliment his style and with VDV's recovery pace alongside that I think we'd be transformed. These players are priceless- look at how Emirates Marketing Project have just fallen off a cliff consistency wise since Rodri got injured.
