With what? We are weaker for sure, when them, by the time you will face them next year, they will have their new signings playing from January, plus will defenitely sign more players.
Depends
Comparing that game to a potential new one :
Defence is somwhat the same, tho bonucci could improve further. We lose vidal in the midfield, who nutered himself in the first game by that early yellow. But we''d have a much better Pogba. Morata will have improved further, Mandzukic gives an actual option to go for, and tevez went missing in the first game, who knows wether dybala will explode ?
Juventus, could be better then last season. Vidal out, but no pirlo in the midfield ? Could be better then you'd think
Barcelona ? How can they improve themselves ? They might be as good as they were, i dont see them improve further.
We were the weaker team. We'll still be the weaker team. Difference should be smaller and we'll have a much better defence thanks to the midfield.
"rip them to shreds" is offcourse a silly statement
