PSG does not need to spend much to compete in the French league. But this team's only target was never the league, they always targeted UCL and they spent accordingly. Now they have removed Mbappe and sold him, they need to make transfers to fill his place, for this they need to make a lot of meetings, convince the players and managers, work extra hours and at the same time increase the offers for the players they want.
That's true because they had big plans long before Luis Enrique arrived but they always failed to achieve success in the Champions League. To compete in Ligue 1, PSG doesn't need a lot of money to recruit other players because the strength they have now is much more sufficient and no other team has been able to break PSG's dominance for so long. Mbappe's departure will certainly make space in that position more problematic and when playing in the Champions League it will be a bit difficult for the attack line to score goals.
That is why it is important for PSG to bring in players who have experience so they can help PSG to compete. Luis Enrique definitely has the right replacement and maybe it's only a matter of time before we see the right replacement. The Champions League is always a target for any club and it is also a big target that PSG has not been able to achieve.
It's saddened that after several attempts by PSG to try to bring this trophy home ,PSG has been this unlucky despite the fact that they've had the presence of these trios MNM, Mbappe, Neymar and Messi play in same team and now that Mbappe who happened to be the last two leave the team, now I don't know what would actually be the faith of PSG in the Champions League competition and with the player replacement for Neymar.
