Messi, Neymar and Mbappe all are still continuing in the World Cup which must be worrying news for PSG. Because even if one this great trio gets a serious injury then they might have a really big problem against Bayern Munich. PSG have got a very tough draw in last 16 round already. I assume they were hoping to face a weaker team. Now it is more important for them to keep their best players healthy.
Especially Neymar is very injury-prone. He already got an injury too as you know but he is good now. If he gets another one then it might be more serious. Because we are in the later stages of the World Cup and teams would try to defend their opponents harder then before.
PSG will be effected the most with this world cup with how many players are still active for their national teams. For PSG is good that champions league is still 2-3 months away and ligue 1 dosent put much presure on them because they can even play that league with a second squad
PSG is now just 5 points clear of Lens A in Ligue 1. So PSG will have to perform well in every match after the World Cup and widen the gap with Lens. Otherwise, it will be difficult for PSG to win the Ligue 1 title. PSG will probably not get all their main squad players after the World Cup. Several players are likely to face injuries. PSG coach Galtier must keep his match strategy tight.
