Denis is another argument, not going to get involved in it considering there is already big debate on him in his thread IIRC
For Alena, I honestly wanted him to play way more this season. But I understand where is EV coming from.
Barca right now is brutal for coaches, one bad season and you will be considered awful for rest of your career (Tata) and winning a treble will get you the overrated label but would at least give you a chance to continue coaching big clubs (I think, will see how it goes with Lucho)
For EV, coming into a season with his appointment being questioned (with fans wanting Sampaoli) , Barca losing 2nd best player, people trying to get Barto outside of the club, lots of drama in transfer window etc I can understand him sticking with the more experienced players.
Also, there is a part of it because of the team and standards we have as a team right now being way higher than it was under Rijkaard, LVG or even when Pep was 1st appointed.
I hope that once we win the league this season (or hopefully more) there will be less pressure on EV and he will start using youth more.
But if he opted to loan Alena I would get it, because he is clearly not that ready right now
Other than Grimaldo, Lucho has proven right with most of his youth players tbh. He was a bit unlucky with the youth players we had. Pep has promoted as much youth players as Lucho in his 1st 3 years and unlike Lucho all (along Thiago in his 4th season) were playing with him in Barca B. Pep proved later that he isn't really a coach who count on youth and god only knows how many he would have promoted if he wasn't a Barca B manager.
What Lucho was offered were a generation were the likes of Munir/Sandro/Samper/Halilovic/Adama/Gerard along Grimaldo was the best that Barca B could offer. He gave all fair chance (again, with exception of Alex)
The academy was fundamentally not working, Lucho has helped Rafinha & S.Roberto massively and gave fair chance to Munir & Sandro along with Samper (for Samper it is up for debate)
Depends on your definition of Barca CM, was Iniesta during his career an AM or CM? for me he was AM and that is how I see Alena. for me he is anything but Barca CM. He is always the most advanced player in receiving the ball and excels in creating things in the offensive end rather than controlling the tempo etc.
