Let's me 100% clear about something right now defending is the easiest thing to do in football, there is a reason why the sport is so low scoring and damn near every manager in the world develops a defective approach first.
So to praise him for improving the defense isn't say much especially given the fact that it as come with a back word step in attack & by playing a bunch of work horse in midfield it really isn't anything special. If you can keep a clean sheet and have Messi & saurez being effective you will win most of your games.
The fact that he cannot integrate what are cleary better player while maintianing a good defensive shape speaks to his limitations as a manager, because there is nothing that Gomes & Paulinho can do defensively that dembele & coutinho can't, because all the do is basically absolutely nothing anyways, maybe help on corns that's about it.
People act as if we lost the league last season by a million points, we were a few points behind even with Luis fuck ups,the man is just a timid little man who is afraid if risk.
