At least they have to be in the top 4 and can be in the Champions League for the next season. Becoming a champion is not impossible, but it takes a lot of luck to achieve it. Juventus must be able to recover quickly and get back to winning after winning to achieve what they want. Their chances of being in the top 4 are still very big, so they have to fight for it. This is a very crucial time for them to get points after points, don't let them miss it, the point is they have to get more positive results in the matches they play.
Getting into the top four is not difficult for Juventus because they are currently in fifth place and only two points behind Lazio in fourth place. Juventus need to make big changes for next season and they can do that from now on. Consistency is indeed difficult to maintain when you don't have quality players, but the problem for Juventus is not because they don't have players like that, but they lose the momentum to get wins in every match. This is what the coach needs to evaluate and maybe they have to improve the performance of the front players in scoring goals in every match.
