I read the news from Sky Sport Italia, Dybala still has a chance to appear in Qatar. but Dybala should be out for four to six weeks, he is claimed to still have enough time to join the Argentina squad. but if it turns out that Dybala has to miss out due to his injury, there are still other names to replace him.
Argentina still has Lautaro Martinez, Julian Alvarez, and several other names. Messi, certainly not serious injury. Likewise with Di Maria, some news claims Di Maria only needs a month to rest for his recovery.
On the other hand, IMO, losing N'golo Kante, Lucas Fernandez and Pogba, will not have much effect on Didier Descamps' squad. they have several names for a suitable replacement candidate. Didier Descamps only needs a mature strategy and chemistry between the players.
Here all is right as many big teams have enough luxury of quality players which can give them good replacement options even we can say some quality difference will surely happen, but things could be on good level for them, and they will be able to perform good without their key players specially teams like Argentina, Brazil and France which are having enough players and most their players are involved in top class clubs with good experience and skills.
But, fans surely going to miss few players those are involved in good combinations which are going to be useful for the top teams specially like Dybala and Paul Pogba as most chances he is going to miss world cup because things are not favoring him for joining team and giving his best which is also good for the player and his career because this is also important for him to take time instead of doing things in hurry.
