I think we’re definitely playing with two players in midfield now, with Bruno having a free role ahead of them. I agree that Mount is a goos fit for the 8 position but we don’t play with it, except at the end of games.
The websites I look at for stats (Whoscored and Sofascore) also show the change in formation early on in the season, and always list us in 4-2-3-1 nowadays. The Athletic had an article yesterday about our tactical setup that confirmed we abandoned the initial ideas from preseason because of our CDM struggles.
