Outside of Ronaldo & Messi for me he was the most enjoyable player to watch over the last 10 years you just couldn't touch him no matter what you tried to do he'd find a way out and he's one of those players who's probably going to be appreciated more after he's gone than he was when he was there because he wasn't always the guy who got the headlines.
Assume he's off to China, MLS or middle east for a retirement pay day but what a career he's had and in Spain he wil always be a hero for that goal in the world cup final.
I thought I'd seen something about a move to China depends on how he feels about travel he might have been to China a few times and liked it I imagine it's a bit of culture shock but then so would Qatar & USA compared to Barcelona. From a football point of view why go to the middle east I mean the standard is shocking even compared to Chinese Super League and MLS it's really poor it's clear if you do that you are just doing it for the money.
In a passage from Iniesta’s autobiography he talks about Paul Scholes.
Iniesta: “One day in La Masia Rijkard walked in and said, 'Today we don’t train, we are going to watch a DVD'. We sat for 3 hours watching Scholes highlights. It was the best day of my life. I, Xavi, Ronaldinho and a young Messi in awe of him. It was then that I decided to call my first born child as Paul(Paolo). He’s 5 now, and everytime I look at him I remember that day in La Masia."
