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.
Completed participants countries only with Lionel Messi and Cristiano Ronaldo without favorite can talk more on 2022 FIFA World Cup in Qatar, between Lionel Messi and Cristiano Ronaldo have ended era and career with their national country. I think both player give bad reputation for their country and make left 10 player difficult how to make creativity still if Messi and Ronaldo on national team. Always try keep focusing scoring goals by both player between Messi for Argentina and Ronaldo for Portugal, will hidden many other potential player if still have Messi and Ronaldo.
