Maybe so, but for me they are wide midfielders as well as attacking players, Barkley McCarthy and Barry was a very well balanced midfield three. For this team I want two in the middle and three behind the striker. Bit of a different formation from then I think.
similar formation id say
in 13/14 martinez lined the side up in 4231
——-McCarthy—-Barry
Mirallas——Barkley——-Deulofeu
—————Lukaku—————
could swap out Deulofeu for Pienaar , Osman or even McGeady depending on what Martinez was going for
famously against Arsenal it was more a 433 with Naismith as a false 9 and Lukaku right wing. but the above was the usual system
Moyes is also setting us up in a 4231
