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.
The potential for a big match in the round of 16 is very likely to happen, we'll just have to wait for the draw to be made. Everything can change, because we will face a long holiday, so the potential for the team to change as a whole will be very possible. Not only for Paris Saint Germain, but other teams will do the work to improve before the round of 16 is held.
