Xavi - who was unveiled by his new club Al-Sadd on Thursday - has now explained that he felt the Brazilian should have been paying more attention to the hundreds of thousands of fans who had lined the streets of Barcelona.
"He (Neymar) was trying to take my shoes off and pushing me when I was on the edge of the bus," Xavi told Qatari newspaper Sport.

"I said that they should stop messing about and concentrate on the people that had come out to wave as the bus passed.
"These parades are for the people after all. It’s okay to have three or four beers but the parade is for the people and it’s the chance for us to thank them for our support. You can’t just do what you want to do."

Xavi also went on to say that he felt Neymar needed to show his opponents more respect on some occassions, too, after flicking the ball over the head of an Athletic Bilbao player during the Copa Del Rey final.
"This sort of thing is accepted in Brazil but here he will need to learn how to win and to lose," said Xavi.
"He is an extraordinary player who also works hard and is very humble but he maybe just needs to reflect a little.
"If you do that [trick] in the first minute when it’s 0-0 it is one thing but if you do it when he did it… he needs to think about that."
