Maybe, but definitely. there are still other candidates to be considered. if Bayern wins in the second leg over PSG, Bayern Munich will be a team that is highly calculated to be one of the strong challengers in this competition. on the other hand, I am quite optimistic that City will beat Leipzig in the second leg which will take place at the Etihad Stadium.
Meanwhile, if in the end Liverpool and Frankfurt failed by their respective opponents. meaning, these two teams will meet each other in the next phase. in fact, we can not predict it yet. because Napoli is not a weak team. they also have an impressive record, both in domestic leagues as well as in the Champions League. but for sure, we will only be able to wait until the round of 16 ends and which teams have the right to advance to the next round phase.
Even if PSG lose the first leg, I think they still have chance to win at the Allianz Arena, as well as Liverpool who will visit the Santiago Bernabéu. Liverpool's chances are very low, but I think good chance PSG can still hope for in the second leg. Also regarding Manchester City against Leipzig, I think Pep Guardiola's team will win and qualify for the quarter-finals.
PSG, Real Madrid, Manchester City, Inter, Napoli and Tottenham are the teams I think will qualify, but several other teams seem to have the same chance too even if they have lost the first leg.
