Juventus have been going through a lot of poor performances in the lead up to the World Cup. There were many injuries in the team which affected the team significantly. If Juventus want to do well, they need to return to good performances. However, I believe that whatever qualification players Juventus have, they will surely be able to return to performance.
Juventus is having terrible start of this season with too many injuries hit them badly, and they were struggling badly for having any positive mark in this season, but good thing happen as now they have good recovery in last six weeks and with this performance they are at the third spot in Serie A which is surely good news for them before this long break, and now they have to wait for positive things if they want to stay at the top and their players could be also in better shape after the world cup.
If they have no injury during this world cup and their players could be in good shape then surely we can expect good fight at the top of Serie A as all teams will try to catch Napoli which is clearly having very good gape and still capable of leading things with quality and performance.
