A lot of people are curious about PSG's performance without Mbappe and other star players such as Neymar and Messi at this time, this is always the main topic in the French league 1 conversation.
To be honest, I lack confidence in Gonzalo Ramos and Kolo Muani because they have a big difference with Mbappe as the spearhead of PSG's attack, in terms of speed they can still be beaten by Mbappe, but Luis Enrique is a pretty smart coach and can adapt to the team's situation, but it is quite unfortunate that in the past season PSG did not win the Champion league which was the biggest hope of PSG.
I quite agree with you that in the absence of Mbappe PSG can save more money in the coming season, if looking for another star player, who is a player who should be considered at this time to cover the position.
I don’t think PSG had the goal of winning the Champions League last season, although when they got so close to the final, I’m sure they started thinking about it. Of course, it is possible that in the absence of Mbappe some other forward will be able to take on the role of leader in the attack and reveal his potential, but this rarely happens, especially since PSG want to get a quick result, so they want to buy a good forward who can immediately take Mbappe’s place and start scoring.
It is not impossible for every team to win the champions league, it is the dream of teams in various leaguers because it is the most prestigious league among big clubs and getting into it is also not easy, it's just that maybe PSG couldn't penetrate further either in the champions league last season or before that.
This is indeed quite a question where we do not know a worthy candidate who can replace Mbappe for PSG, Enrique may have other plans or indeed he feels enough with the players he has today to test the upcoming season, maybe it will be left to Kolo Muani if the situation does not change.
