Messi may think of his old age more calmly than having to go on the field again, but it will only make him unable to enjoy life in his old age.Messi's youth was full of struggles until they finally made him one of the best legendary players ever, so it was only natural when Messi thought about retiring at his old age.
Messi is not yet thinking to retire from the professional league. he wanna try to go back again to la liga as he feels that la liga is always become the best place for him. Messi's father already confirmed that if messi is still wanna playing in europe too. Al hilal has been offering him very big amounts of money. Messi will able to receive more than 1 million USD everyday once he will be joining in al hilal but it seems like that if this will be dilema for him. Messi can still have the intention to play in europe but the problem is if messi will not also able to get the same offer again.
Messi will be old and he will never play football. It will be better for him to enjoy his life when it will become even older than this time. Money is not everything but everything needs money this time.
I can imagine how big money will be received by messi if he will agree to join al hilal. If barcelona is still struggling with FFP until next transfer season and i think that the chance for messi to go to the barcelona is very small.
