Even if Deulofeu has got some problems it is lucho job to fix them
Lucho knows more about him and about his current and future abilities, than we do.
He either:
a) thinks that Deulo will never be good enough for Barca, but sent him on a loan to give him a last chance to prove himself there and earn another chance in Barca in a Season or two
b) thinks that Deulo could be good one day, but that that he is knowhere good enough for Barca currently, and that Lucho doesn't have too many room to give him first team chances in Barca this Season.
So, his only chance currently is to go somewhere else and to regularly play.
BUT! He will have to be awesome in another club.
Another average or poor senior Season surely won't bring him a new chance in Barca, but another loan next summer, or he will be sold.
So, he will have to shine this Season if he wants to get another chance in Barca.
People here are assuming the option:
c) Deulo is good enough already and only needs to be given chances in Barca and everything will happen "naturally"
Plus, he will surely be a first 11 material for Barca in the future.
Lucho doesn't think that way, it seems.
Either is Lucho wrong, or forum members are giving too much credit to Deulofeu.
Again, what has exactly Deulo done till now on a senior level to get a chance in Barca?
Not too much, except that he is being hailed as the greatest current La Masia potential.
People say that Lucho should teach him and "fix" his flaws, like not tracking back, low workrate, selfishness (or even the attitude problems) etc.
Maybe Lucho thinks that these skills are such a huge part of Deulo's style and personality that they aren't repairable.
Lucho knows much better if his flaws can or can not be fixed.
If the flaws are so big, none coach in the world can fix them. They are just part of the player's skills/playing style/DNA, and he will carry them forever.
Lucho probably thinks that his set of skills/player's personality is not what Barca needs (maybe only currently, maybe forever)
