I disagree with you that Juventus played well. Juventus has been playing very badly lately. Their consecutive points losses show that we are correct in this regard. They were competing for the leadership in Serie A, but they are now far from that race and are entering a race with Milan for second place. They may be lucky if they can get the top 4 places at the end of the season. Because they played very badly in their last match.
With just one win in the last seven matches, these are not just bad results, in fact the results are terrible. Alegre receives a lot of criticism, in fact it is not clear whether he will remain in the team, I suspect that everything is already decided there and everyone knows about it, but this is not allowed to advertise. Hence such a bad game, Alegre may be looking for a new club, the players again do not understand what to expect, that’s why there is such confusion. Yes, Milan has already bypassed Juve, a little more and Bologna will get closer to them.
I think Allegri was criticized when he returned to Juventus because, while Allegri returned as head coach of Juventus, Allegri failed to make Juventus consistent in the title race. So, I think it would be very strange if Juventus still kept Allegri for next season because it is clear that Juventus needs a change and not just to keep Allegri who has clearly failed. So indeed, even though at this moment Juventus is still in the top four of the Serie A standings but yes, in reality Juventus is unable to maintain its position in second place and clearly, that is a bad result. Because afterall, at least Allegri only needs to make Juventus strong in Serie A this season but still, Allegri failed miserably and is not worth keeping.
