I am not underestimating Juventus, I would also love to see them win the match, but their performance is not something that one can count on at this point of time. They might even draw the match. As for the prediction on the other matches, I don't have anything to say.
Maybe he doesn't underestimate Cagliari, but he is more confident in Juventus. Mid-table teams are sometimes too easy for the top teams to underestimate, but for betting it's not about underestimating opponents. We can see from the statistics of the Inter Milan and Cagliari game, Inter only took a total of 15 shots, and only 7 were on target, I think in this match the cause was Inter Milan lack of efficiency in scoring goals. And, a mistakes happens, there was miscommunication in Inter Milan defender in the last 10 minutes which making Cagliari able to equalize the score. As long as Juventus doesn't make the same mistake, I think it's fair for him to bet winning for Juventus.
but let's hope that there is a victory for Juventus finally, I'm tired of seeing the team suffering with poor teams, let's also consider that there was a lot of bad luck in the derby and that Vlahovic took a full post but currently we're not at I don't know how high it is to go to Europe and compete with teams like Galacticos or MCI. I just hope we can unblock this situation..
Although Inter only drew 2-2 against Cagliari, but I think Inter not underestimated Cagliari. Because anyway, basically there are no more challenges and competition happening at the top of the table and therefore, it will be a natural result if the top team then fails to get a victory in a particular match. Because after all, even if Inter only get a draw or maybe a few defeats too, in fact Inter will still be at the top of the Serie A table. Therefore, results like this are not about underestimating or not, because results like this are very likely to happen in situations like this.
