Well, the idea is that this team is full of "young" Gods, so it kind of implies that while Vidar might be that strong in the future, he may not be just yet.

What's more, Fenrir remarked how he was scared of him "now", that would be the important thing to note, Fenrir isn't even half as strong as he used to be, so it makes sense that he's scared of Vidar now, who kills him in his original state.

Chances are even if Vidar isn't Top 10 level now, he is still stronger than Fenrir. However, for the sake of the tournament, I feel Typhon is the only one on that team that is going to be in the Top 10, and thus, the only one who is an individual threat to Issei. As for the rest of the team, we don't know quite how strong they are, not all Gods are Satan-Class or above. There's a strong possiblity that since they are "young" Gods, they may be Ultimate-Class or a weak Satan-Class, meaning Issei's team should be able to handle them.
