Pochettino wants messi union at newells world cup win for barcelona icon in 2022

I think there may be a few issues with the statement you provided.

Firstly, Mauricio Pochettino is a former manager of Tottenham Hotspur and Paris Saint-Germain, but he has never managed Newell's Old Boys, a Argentine football club.

Secondly, Lionel Messi is a Barcelona icon, but he has never played for Newell's Old Boys. He joined Barcelona's youth academy, La Masia, at the age of 13 and has been playing for the club ever since.

Lastly, the 2022 World Cup is a tournament for national teams, not clubs. It's unlikely that Pochettino would want Messi to win a World Cup with Newell's Old Boys, as Messi has always represented Argentina at the international level.

If you meant to say something else, please feel free to clarify!
