Real needs to sell one of their attackers and make a push for Pogba if they want any chance to compete with Barcelona, even though I think dude has his heart set on Barca.
Benitez has his work cut out to pick the right line up and keep his players happy. It seems like an impossible task since a no-name player who came out of nowhere in Casemiro has cemented his spot in the starting XI.
Flo won't allow Bale to be dropped ever, which complicates it even more.
Most likely means 2 of the 3, James Isco and Benzema will have to ride the bench.
I wouldn't mind seeing something like
Bale Kroos Isco
Modric - Casemiro
Ronaldo isn't beating anyone on the wing anymore, dude is still an elite penalty box predator though. Someone needs to remind Bale he's a left back and get him to defend and charge down the wing again. Not fail at cutting onto his left from the right. Also I think he can feed off Kroos, Modric, and even Marcelo lined up like that. Really any of the 3, Isco/James/and even Jese can play where I put Isco. James is better and more talented but Isco is the better and more willing defender. Either of the 2, Modric or Kroos can play the 10. Only thing with this lineup is that some of the fits might be awkward, but I think collectively it provides balance.
