We most definitely need to add greater and better depth pretty much everywhere, i'm still not convinced by Varane at all and Nacho at CB can work against most teams but not against the best ones. He's better at RB. And we still need another CB anyways because Vallejo barely played at all this season and not for lack of opportunities.
As for midfield, i don't think kroos and modric will be better next season, at least under zidane. They just don't look hungry anymore to me. Couldn't even follow some basic tactical instructions all season long. Perhaps it's because they played too much over the last 3 years and it was a matter of fitness, but the way i see it, they just don't really care enough anymore to put that extra effort in...
Up top we've been saying it all along, sell and replace Bale, upgrade on Benzema.
We seriously got away with it against bayern, they whupped our butts for 180 minutes. At the very least we need a whole new bench. That is major surgery. We have 4 useful bench options right now, and we will finish the season having played 62 games. With another 60 last season, and 52 the one before. Plus internationals, the Euros and the upcoming WC. We need reliable fresh blood, badly, and in great quantity
I said add a better RB backup and use Nacho exclusively as a CB and you said the reverse... either way one backup defender in total, two if we're really pushing it and aren't willing to give Theo, a teenager, more time, which I'd disagree with, though can see why some might see it that way.
Modric not caring anymore? What did I just read? He's still the best MF in the world, last night against Bayern included, I don't know which Modric you've been watching. Same thing with Varane. And while Kroos has had a dip in form for sure (though even then he was crucial in finding space for Ronaldo which resulted in our penalty vs Juve), he'll be alright, he's way too professional to stay like this for long.
And we've got Isco, Asensio, Casemiro, Kovacic, Lucas who can be starters for almost any team in the world, heck even Ceballos would be a starter for most clubs. Basically we've got so many midfielders with different profiles, we don't lack options in that department for sure, if we look at the bigger picture esp. during our league campaign, our main problem wasn't not creating enough opportunities but putting the ball into the net (earlier in the season Ronaldo wasn't on a good form and we couldn't score no matter what which is why we're way behind in points while we used to have Morata), and it just built more and more pressure on the team... and when you don't score, you're far more likely to concede.
So I think as long as we address the problem with scoring (someone to share the burden with Ronaldo) and get a pacey RW as well in place of Bale, for our counter-attacks, we'll be more than fine. I see no need for major surgeries, honestly the way I see it is while you're a decent poster, no disrespect but sometimes it's like you consume too much Spanish (or similar) media and have that overreacting attitude.
