Lucho's recent work has been brilliant. He's managed the players extremely well, they all play with desire and they work with a very high amount of professionalism (very unlike recent years). Tactically speaking, he has fixed the right flank issue with Alves now acting as a midfielder and Rakitic in a very comfortable support role that brings the best out of him, not to mention Messi playing at his best level on the right. We've also got awesome variations in our play and our transition is unpredictable. We can go long, short, fast, patient, wide, central, pretty much anything. We excel with all options now and can change at will on the pitch. Barca have faced both high pressure and parked buses in the recent months and have had answers to just about anything.
His relationship with the players interests me. People have noted that he deliberately keeps a distance and uses his psychologists as a medium for communication with individual players, which I agree with. To me, the motive for this is to build a trust mechanism. Lucho has not been the most well liked coach and has had a shaky overall time here (pre-January). If he can keep things calm and professional right now then the players will rally and keep up with things. If he can build at least a somewhat long career at Barca (>1-2 seasons) then I think the 'distance' will reduce because he'll be trusted more and looked towards by the players for answers. It's easier to build comfort with players as a coach when you have merit and I think Lucho is slowly acquiring that. It's unlike Tata who left himself vulnerable to a lack of response from the players because they didn't take him as seriously and work with the same level of focus or professionalism. More results=more coaching merit=more trust=better relationship with players=better response=more results. An awesome positive cycle can be built from this and Lucho seems to have figured that out.
