Real Madrid has solid midfielder and Carlo Ancelotti has many option when rotation in this position, but Madrid has little option with attacking line actually after leaving by Karim Benzema and not official confirmed yet who will replace on center forward position. Jude Bellingham is good option for Real Madrid how regeneration with midfielder position, he can play well as attacking midfielder and replacing Luka Modric position, but still can't guarantee for Jude Bellingham easily for getting regular position due how compete on midfielder position with many potential players there.
Ideally, Real Madrid's midfield for next season should consist of Valverde - Aurilien Tchouameny - Camavinga - Bellingham.
The four talented young Real Madrid midfielders must often become regular starters in the 4:4:2 formation because maybe this formation will change in the second half to become 4:3:3.
Not to mention that later there will be Brahim Diaz and Dani Ceballos who will cover for Real Madrid's attacking midfielders in addition to Toni Kroos and Modric as seniors or permanent starters, Real Madrid next season will have many top midfielders. In my opinion, the 4 : 4 : 2 formation must often be used interchangeably with the 4 : 3 : 3 formation. But Real Madrid's biggest mistake is if there is no striker to replace Benzema, next season's competition will not go well, even though there are many young players.
