PSG is very likely to suffer defeat in the first leg of the last 16 of the Champions League against Bayern Munich had it not been for Messi and Mbappe. Then Neymar will not really perform optimally to win the match because Bayern Munich is a solid team. It's possible the news is true "maybe it's false" and Messi will miss the match against Monaco and Bayern Munich, but I have no confirmation so far.
After all, if Messi and Mbappe were injured and missed the first leg, that would never guarantee Bayern Munich a win over PSG. There is always an opportunity to perform well and win, this applies to any team even without star players.
Obviously if this happens then PSG will suffer a bigger loss in the first leg maybe it could be a defeat because it is lacking in attack but I am sure PSG will not be that weak they will definitely be ready for everything that happened against Bayern Munich in the first leg, so we should never underestimate any team even though Bayern Munich are solid in the UCL but believe PSG can overcome trying not to lose in the first leg.
There are two players I love who are injured. There is a doubt over Lionel Messi's participation in PSG's Champions League first leg against FC Bayern Munich. In his behalf, I am not worried at all though. In the absence of Messi or Mbappe, the rest of the team should have the ability to pull through anything they face. Perhaps this is the best opportunity to show off their talent. They will succeed if they are prepared to give their best for the team. There is no doubt that Bayern Munich is one of the best teams in Europe. By embracing challenges, PSG can achieve better results. Bayern is just a name, if PSG become nervous, this could put them at risk. Then Bayern qualifies and PSG will be eliminated.
