This is the fourth time Juventus have failed to win in all competitions in their last five matches. Drawing with Parma, Thiago Motta's team missed the opportunity to rise to the top 3 on the rankings. I don't think it was entirely Dusan's fault, although he missed a chance to score. The main reason I think, their defense has continued to show uncertainty in recent times since losing Gleison Bremer to injury. When even a consistent player like Pierre Kalulu makes unbelievable mistakes, the concern about the defense without Bremer is getting bigger. Not to mention the problem of overload and the storm of injuries sweeping fiercely.
I think Juventus don't need any transfer activity, the best thing they can do is improve their attacking performance, in which Yildiz is a key player who needs to be used and promoted wisely.
I have to say this is just a unlucky situation to miss those chances, not everyone has to have wins. Look at how they made a comeback against Inter, that was a great game, this one was just unlucky. Dusan Vlhavoic is a great striker normally and he just had a bad game, every player has bad days and there isn't a reason why they should eb worried about it and they can do a lot better on the long run.
I believe the best thing on their list should be just focusing on how to get better results without dropping their morale. I understand they may not be winning for now but I think they are going to go back to winning if they stop caring about previous games and start caring about future games. Vlahovic will do better and they will get the results.
This won't be easy, they have been unlucky for a while, of course they are going to face some trouble when they are playing, but that doesn't mean they are going to do terrible, they should be doing fine on the long run. Things will even out, and Juventus will start winning some games again. This isn't some sprint, league is a marathon and while they may have lost some pace for now, they can still outpace their opponents for the rest of the season.
