Since the first time Mbappe blew us out I was in favor on bringing Haaland instead of him. It was not only because he rejected us but it made more sense to bring a striker or a player who would operate in the center.
Honestly, with Mbappe in the team and Kroos retiring, both the options from last year which maximised team performance (Bellingham false 9 or Joselu/Brahim Diaz up top) are gone.
You can't play Bellingham false 9 anymore and play Mbappe one wing and Vini left wing, because without Kroos, Camavinga Valverde and Tchouameni (40 year old Modric can't be a key player) simply don't have the creativity to feed the runs that Bellingham was making or the pockets of space he was finding between the channels. Without a creative deep lying playmaker, you therefore need a ball carrier, but the problem is none of those three other than Camavinga are specialized in that either.
Which means you have to drop Bellingham deeper to carry the ball forward and provide the creativity.
So you could go for last years approach which is use a makeshift number 9 (in last years case it was Joselu and in some cases Brahim Diaz), but then with Mbappe and Vini drifting left, the right doesn't have cover. Rodrygo also drifted heavily to the left but the difference is Rodrygo has a much higher engine and work rate compared to Vini and Mbappe and could cover for gaps and track back.
So if you stick a midfield of Camavinga/Tchouameni, Bellingham and Valverde, the problem then is that when Valverde attacks the space on the right that Vini/Mbappe generates by drifting left and Brahim holding the center, there's a great big hole in the right side of the midfield. Last year Rodrygo and Valverde held that because both are hugely willing to run, but whoever you stick on the right side out of Vini/Mbappe won't do that.
I think the only way this works now is if:
Vini - Mbappe - Guler/Brahim
Camavinga - Bellingham - Valverde
Where Guler or Brahim are explicitly asked to hold the width on the right side and do not drift in, which may be very difficult given both of them dribble and prefer their left foot. But Rodrygo simply cannot maintain tactical discipline to not drift over to the left.
Even then this is very dangerous because you have to expect Bellingham to cover Valverde, be the main creator/ball carrier for the team and exploit the gaps in the channels. Too much on one person.
Yeah, I dunno, Real's squad is hilariously unbalanced.
