I'm not gonna say alexis is pure shit but come on what does he bring to the team that enables him to warrant a starting position THIS often.
Pedro has more than plenty off the ball movement to occupy defenders and he brings in a huge workrate.
Tello has raw speed that allows him to be unpredictable.
Villa also does lure away defenders and occupy them because he is a big scoring threat and is a great finisher.
Cuenca has his pinpoint crosses and calm mentality to boast.
And they all have a fairly impressive dribbling ability. What does Alexis bring to the table. He's clumsy and has no balance whatsoever, he dives, he can't control a ball for his life, He stunts all barcelona attacks by trying too quickly or too hard, and he loses possession way too much, and he can't finish. Once in a while he does something right and makes a decent pass or beats a defender but i'm pretty sure thats not why he's supposed to be playing. I'm not gonna say he's extremely horrible because it takes some level of talent to be making regular starts for Barcelona. However he gets playing time handed to him way too much when players like Villa, Tello, Deulofeu, and Cuenca work their asses off and get results for no recognition.
Obviously barca is doing amazing right now so it's not a huge point of concern. But think about it, Barca are starting the knockout stages of the CL soon and thats a time when they should strive to correct every possible mistake and leave no mercy for the opposition. Especially if messi were to possibly pick up an injury. In the league, we can handle a loss or something because we have a huge lead to fall back on. In cup competitions, one loss makes a huge difference. And I'd rather have our attack be devastating on all fronts instead of cutting loose on a few ends. The opposition team should fear every one of our players that step on the pitch and at the moment Alexis isn't one of them. He could pick up form and become a team star but until then, he can't be protected like an innocent child for playing bad.
