Both Messi and Ronaldo countries don't have the best team on paper in this world cup. This is likely their last worldcup but these legends might still want to have few games with their national side after the world cup. In terms of an identity, cohesion and commitment, the Argentina team seems to be slightly better than that of Portugal and hopefully it will be a great worldcup for Messi.
I supported the Argentine national team when Batistuta played there and then for some time due to inertia, but now I will wish that this team did not go far in the upcoming tournament. I'm a little tired of the hysteria that is inflated around Messi and the last event (Argentina - Italy) reminded me very well of this. Argentina won and again from every iron I heard about Messi's genius. Please, I've had enough

I'm even beginning to think that Messi purposefully preserve himself for this world cup because I didn't see him have that usual great performance from him this season in PSG even with Mbape and Neymar by his side. I believe he reserved strength and he's going to show spectacular performance in this very world, which this might be his last world cup to play because both him and Ronaldo got no time by their side amore.
For C.Ronaldo I think he might find it difficult to shine , looking at he's performance this season and this last game they played, Ronaldo now lost in games.
With the look of things now, I don't think Messi or Ronaldo will end themselves a world cup, cause alot of countries are well prepared for this. And we all know this might be their last appearance in world cup, and these is the only thing they are lacking as a player. Though Messi side Argentina are performing better recently but I don't think that might hand them the world cup when we have some nation's like Belgium, France, Germany, Brazil and England. I think the world cup won't be a easy fight this year, so these players needs to be in their best performance knowing fully well is their last world cup.
