Absolutely, every club experiences both good and bad times. Juventus has performed well from the start of the season, but we don't know what's going on with their performance right now. Juventus has competed with Inter Milan for the title this season. I believe it is too late to judge Juventus at this moment, with the games left, Juventus still has a chance to finish the season in the top four. Juventus' current players are capable of winning their remaining games. M.Allegri's goal at this moment is to win the rest of their games and finish in the top four, because they are currently two points ahead of Bologna.
8 matchdays ago was the championship game against Inter Milan and they lost it 1:0. Since then they only won 1 game, I dont think they had such a bad run all season. 17 points away from first place and 6 points away from 2nd place. The championship has not been possible for many weeks, now it is only enough for a place in the champions league next year. Since february juventus has not been playing so well and that is now 2 months and I think there will be more weeks to come.
