PSG is a big candidate for the title winner this season because this season PSG have a deadly trio up front, this is what makes me believe PSG can beat their opponents in the next round. Real Madrid have a winning mentality and their squad is also very strong for this season. Bayern munich and manchester city are among the strong candidates for the title this season seeing their performance in the domestic league and in the ucl is very impressive for this season i think they will try hard to get the ucl trophy. Maybe we shouldn't forget Napoli they are group winners with a pretty good performance so far.
I'm still not too sure about that, especially in the last 16 there is a possibility that they will face a Big Match considering that they have to be in second place in the group phase so it is very likely that they will do the same Big Match in this phase as last season.
In terms of players in the squad they are still very decent but of course this is not only a matter of players but the coach's scheme is also taken into account and you could say Galtier is a debutant for the Champions League so this could be something that is indeed the same as last season.
