I don't think 3-5-2 with Chilwell and Albrighton wide would make us narrow.
Agree that diamond formations haven't worked, but 3-5-2 would give the wing backs more license to get forwards.
I hear what you're saying Graz, but the reality IMO is that our full backs do best when getting forwards when they can overlap and join in with whoever the wide player is ahead of them. Chilwell in particular doesn't take players on, but even Ricardo, as good as he is, can't do it alone. They benefit greatly from having a wide player there ahead of them, who they can work with or off, rather than having to do it by themselves. That's why when we play in a narrow manner, Chilwell often gets grief, as he checks out of an attack and comes back round, as he has no option to play with. They may be able to "get forwards", but that's not much use if it doesn't lead anywhere.
I said this before the Villa away game in the league, and we won (albeit with a diamond), but I maintain that it doesn't play to our strengths and, despite it working that day, I can't recall another occasion when it has.
The concept of a diamond, compared to a 3-5-2, is the same in regards to the fullbacks. Yes, they may start slightly further forwards and have another defender behind them to cover, but we lose the overload out wide and end up like England in the Euros in 2016 against Iceland, when we looked devoid of ideas.
While I'm on my soapbox, I don't like it when we play with two defensive minded central midfielders either (especially against Brighton at home
). We lose whatever creativity we might have and become too pedestrian. Where's the energy we started the season with gone?
