I don't think Lucho is cut out for a job of this magnitude (at this point in time anyway), but it's certainly not all down to him. The only real issues I would see there are the way he wants his MF to set up (stretched to cover the fullbacks) which leads to a massive over-reliance of creativity on the forwards, which basically amounts to Messi, and a lack of combination play to open up the centre, plus he seems to rotate his DF & MF quite often but at strange intervals (seemingly can't decide who his starters are going to be either). Issues that stand apart from the manager are to do with the relative physical declines of Xavi and Messi in my opinion. Iniesta is a riddle, apart from perhaps psychological issues, there is really no indicator as to why his performance level has regressed so much in such a short amount of time (from probably his best ever individual season, 11/12, to two of his worst, 12/13 & 13/14). Neymar has done very well to show his clinical touch, but he brings very little constructiveness to the build-up. Suárez is still too early to tell, but I'm convinced of one thing already, he isn't at his best as a 9 (unless it's in a counter-attacking side). At Ajax he played with Huntelaar in his first season, then Huntelaar/Cvitanich, then Pantelic and finally with El Hamdaoui. At Liverpool in his first full season there was Carroll and after that Sturridge acting as 9s. The only exception is for Uruguay where he has led the line in exemplary fashion, but then there is a clear and obvious break in approach between Ajax/Liverpool/Barça and Uruguay, ie. the former use a high-line, possession based game (Liverpool under Rodgers anyway), the latter rely on defending deep and verticality in transition phase. In the former type structures he's clearly at his maximum level as a second striker. Evident from the way he has consistently attempted to roll his marker whenever he receives the ball with his back to goal around the edge of the area, but keeps getting caught out because there is so little space to work with when playing for Barça. He's at his most dangerous when he can receive the ball to feet first time before his marker has a chance to set himself, which is the total opposite of what Barça do. Yesterday, Emiliano Velázquez (his promising 20yo compatriot on loan from Atléti) had him in his pocket because of it. The positives with him have come from chance creation, yet again yesterday (in an otherwise poor display of technical ability) he pulled an inch-perfect cross from nowhere, putting it on a plate for Pedro to tap home, but the latter somehow failed to connect.
