Do you have a good win rate with betting on all the favourites on the same week? If you do then no problem. Otherwise you are probably throwing away your money just for fun my friend. 

The first one already won, congrats! But for once I was worried Juventus wouldn't be able to win as the goals came really late.

For the rest, I can only say Como and Milan seem really risky. Both teams are unpredictable these days.
