Yeah, I agree it is time to re-tool and get younger. I can even live with a "down" season (I mean, as a North American, I am used to them). Ronaldo leaving was good timing, IMO. Guy is 33 and we just had won 3 CLs in a row. Gives us the flexibility to give Asensio more playing time and change the team make-up. Not a bad thing.
Modric leaving? It sucks way more. It would make our midfield much worse. However, the more I think about it, the more I can stomach it. We probably weren't gonna win any major trophies this year, even with Modric, so let's give a younger player experience (Ceballos, most likely). As long as we place top 3 in the league, I think I can live with it. Most Madridistas won't and will be calling for heads if the team is out of La Liga race by December (which is likely considering Atleti as gotten better and Barca should still be as strong as last year). Asensio and Isco will be under tremendous pressure to succeed and Perez better hope guys like Ceballos, Odriozola and Vallejo progress nicely and can be part of an effective "B" team. I like that they have concentrated on getting young Spaniards in recent year, they most be successful now. Pressure will be EXTRA high on these kids.
I also do not really understand the Courtois move. Navas has been a very effective keeper for us. Sure, he had a tougher season last year, but even though I see Courtois as an upgrade, I don't see him as a massive one and certainly not one that was needed. I won't ***** about the move, I just do not really get it.
