Luis Enrique thinking of tinkering his system for Sevilla

It's said that the majority of managers' systems are created by the players he has, not by the way he necessarily wants to play. That's to say that the tactics end up being adapted to the players that are in the squad. Only the most narrow minded and stubborn coaches are unable to adapt, instead trying to shoe-horn players in to an un-natural position at any cost. 

Fortunately, Luis Enrique has demonstrated that he is not one of those managers and that he is able to condition his selection and hios system based on the players he has available. He has shown that since day one.  

The injuries to Lionel Messi and Andres Iniesta mean the Barça boss will possibly have to move away from his successfull 4-3-3 set-up. Without these two vital players to call on, the system may not be as effective, because none of the players Luis Enrique has available in his squad are close to either Messi or Iniesta. So he is studying a small tactical change to make sure he gets the best out of the players he does have. 

In principle, in the final minutes against Bayer Leverkusen -- when the comeback happened -- Luis Enrique had already made tweaks. And they worked. He changed from 4-3-3 to 3-5-2, with two wing backs attacking high up the pitch and three defenders covering. It was a system which led to the best moment of Sergi Roberto's short career. With the return of Dani Alves, the academy product moved back to midfield, and he is showing that he is capable of switching between positions. 

This system deploys Alves and Alba almost as wingers, loading the midfield with five players, which could even become six if you consider how far up the pitch Pique often carries the ball. With more superiority in the middle of the pitch, it helps Barça avoid pressure and also aids the fluidity of their play. However, this system could leave Sandro and Munir sidelined. 

Another option for Saturday's game against Sevilla would be to deploy a conventional 4-4-2, which would leave Marc Bartra as a substitute, presumably
