IMO, it looks like Mbappe will be even more active in targeting the Cgampions League trophy. the reason is, Mbappe failed to present the world cup championship trophy for his country France. I'm sure a young man at Mbappe's age will only get stronger and he will likely continue to train and hone his skills. on the other hand, PSG has no significant rivals. in fact they are too strong to be rivaled by other teams below the ranking. the only, team that comes close to the points that PSG has is, Lens. only five points adrift for Lens, can match the points owned by PSG. after Ligue 1 rolled out, Lens had an away game against Nice. and Nice is not an opponent that is too complicated for them. Furthermore, Lens must face the French giant, Paris Saint-Germain. the reason is, Lens will find it difficult to keep up with the strength that PSG has.
The only opponent that is equal to PSG is Bayern Munich, however, Bayern is currently plagued with several problems in which several of its players are injured. if PSG can take advantage of this moment, it will not be difficult for PSG to win the round of 16 match later.
I think that Mbappe with Neymar and Messi will serious try to win Champions League this year, considering what happened during this world cup. Hope also to not see Mbappe at PSG the next year, I don't like the way of
how they built this team, he deserves a team like Real Madrid, not a petro-dollar team. (But I can understand also, that there are some political pressure about his permanency at PSG).
