Juventus may be interested to sign Conte as the replacement for Allegri but I doubt Tottenham will allow him to leave. Since Conte managed Tottenham, there is a good improvement in this club performance. Tottenham management must try to keep Conte, they will offer an extension for Conte's contract. And I am sure Conte probably accepts the extension to ensure Tottenham plays well until the end of the season. I don't think Conte to leave what he just begins in Tottenham.
Juventus is better to look for another option to replace Allegri. The chance to sign Conte seems rather small.
Even things are not good in Juventus but still there is no fair chance for sacking Allegri and bringing new coach because few days back Juventus management already announces they have faith in him, and they are looking for positive development in coming weeks which is good decision from them because sacking coach in hurry is never been bringing positive results.
Conte is not leaving Tottenham until end of this season with this most chances if Juventus management feels to have some changes then surely they will do this all at the end of this season with there could be some more options also available but right now doing like this is surely more mess up not good for team as we all know having extension was Conte's decision, so he will not leave just after few weeks of this season.
According to what I have seen so far, Antonio Conte is only recruited by teams who are in trouble. During the time when he was appointed as a manager by Chelsea, the club was in a dire situation at that time. Next, when he moved to Tottenham, they were in the midst of a great deal of trouble as well.
Due to Juventus' current struggles in the league, they are also now considering Antonio Conte as their next manager. I am sure that Antonio Conte will be able to do the same if Juventus decide to appoint him as the new head coach, just as he has proven to everyone that he can bring a team back from the brink of oblivion.
