Juventus lost to Lazio recently which is not good. But I think it is too early to say they won't finish in top 4. Juventus has history of coming back strong after tough losses. I believe they will work hard to keep their position in standings. Every team has tough times during season. How they deal with these challenges shows their character. Juventus has good players and coaches so I think they can do better in next matches. Let's see what will they do next. 
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.
Bologna vs Salernitana
this time Bologna has a good opportunity to continue the positive trend when they have to compete against a weak team from the bottom of the standings like Salernitana.
everyone can already tell which team will win this match and of course Bologna has a very good chance with the situation which is currently in a very consistent state.
from H2H history, Salernitana has never beaten Bologna but was only able to hold the match to a draw and I wouldn't be surprised if in the previous match Salernitana was able to hold a draw because weak teams can always provide surprises that we can never predict.
maybe most will bet on Bologna but the odds are very small and I decided to bet on BTTS which has bigger odds and is worth the risk.
currently, even though Salernitana is playing away, I think they can at least score 1 score in the second half.
the current score is that Bologna is ahead by 1 score.
Bologna's performance this season has been really impressive, I never expected them to make it to the top four. Bologna leads Salernitana 2-0 from the first half. Even before the match started, I believed Salernitana couldn't compete with Bologna with their current form, I think Bologna will score another goal before the final whistle.
