Yes.
Yes, He will show the world he does on FIFA 2022 WORLD CUP [My prediction not confirmed]
The 2022 FIFA World Cup will be hosted by Qatar.
Fifa world cup is a platform for countries not the clubs.FIFA Club world cup is for clubs. If Messi will play for Barcelona then who will play for Argentina ?
As the 2018 world cup has still to be decided 2022 world cup is a far off.
