If Denis comes back also, we'd have Iniesta, Rakitic, Roberto, Rafinha, Arda, and Denis competing for two positions. Probably better for Halilovic to stay on loan for another season.
I have a feeling that "idea" of Halilovic as Barca's midfielder is more like a fantasy from our fans and forum, than a reality.
Halilovic has been a winger his whole career.
But since we have Messi "locked" at RW position for the next 4-5-xx years, it seems that our fans are trying to find some win-win solution and now we are "dreaming" about Halilovic as a midfielder.
He "can" play as an attacking midfielder, and he is improving there.
But also, Busi can play as a Cm and Mascherano can play as a Cdm, but they are not at Barca's level on those positions.
About Halilovic:
1. he played as a winger in Dinamo Zagreb
2. whenever he plays for a Croatian NT, he is always a winger
3. whenever he got some minutes under Lucho in a preseason, he was ALWAYS a right winger
4. his Dna and natural skills are=a winger, either in 433, 442 or 451
When Alen played as a Cm?
1. at Barca B, a team crippled with a transfer ban, so since more or less nobody can create anything in midfield, he was pushed at Cm position
2. Sporting Gijon, another horrible team, where he is by far the most creative player, so he is more valuable as a creator there, since no one else can create anything
But I see his midfielder's episodes more like Alexis' episodes in Chile, where he was a Cm or Amc and the main "brain/creator" of his team.
While in Barca, he was always an attacker, and he was never good enough to be Barca's midfielder.
Imo (not you mate, but majority of users), this is starting to sound the same as: Samper should be our Cm (but NOT because he is better as Cm than Cdm, but because Busi is "locked" at Cdm position for years, so our fans are trying to find some other position for Samper, so that we could have as many talented players as possible on the field in the same time.)
I personally don't care how many midfielders we have.
Halil will either make it one day here as a winger.
Or he will fail.
As a Barca's level/type of a Cm or Amc, I personally have 1% faith in him.
He is just not "our type" of a midfielder. Not even close.
