Great story would be nice finish if the BBC could arrange for him to meet Messi.
Hold on.
So he got as far as Dubai by plane, a distance equivalent to London to Madrid. From there he purchased a bike ($700) and had $10 a day for 45 days ($450) giving him $1150 which he could have used to buy a ticket to Russia from Dubai. He has a match ticket so transport is free in Russia so getting to Moscow should be easy. Also Argentina are only a free four hour train journey away and so he could get very close to the team. Once there I'm sure a journalist would take him under his wing. Meeting Messi, that's never going to happen.
All that said, congratulations to the guy and I hope he gets to see a good game, France v Denmark might be exciting or a 'we've qualified' reserves fixture.
AAAGGGHHH
Edit.
Ticket from Dubai to Moscow on the 24th June is £270 Return ticket a few days later is £340
DOUBLE AAAGGGHHH
He could have flown from Mumbai to Moscow same dates. Return price £530
Yes, I'm bored.
