Players with this kind of trait are always going to be predictable. Robben being the best example of this. Everybody and their dog know what's going to happen. It's still almost impossible to stop. Couts might've overdone it yesterday - that's because we were trying to win the match. You may not like it, I personally have nothing against his tries.
Maybe, but Robben for example is much better at going past players, making it easier for him to get into good positions before shooting. Coutinho, although very good on the ball, just doesn't have that ability to progress, or not as easily/effectively, and so he ends up shooting from worse positions. Okay I think that only really happened once vs Girona, but it's happened before too. Look, I like Coutinho, I even like that he can and does shoot, it's a viable tactic against deep defences, I'd just like to see him vary his game more, link up with Messi more, play Alba in more, also cut in and rather than shooting look for the run of the right back more. For me he's a bit goal-blind, as in makes up his mind to shoot and ignores all developing options. There was one occasion against Girona I remember screaming at him for reverse ball to Messi, but his mind was already made up.
