The former Barca coach is convinced the combination can work.
"Will Messi and Neymar work together? The best player of all time alongside a brilliant footballer? I’m sure they’ll work together," he told the press.
"Barca and Spain have got a lot of longevity. It’s not unusual that Spain lost [to Brazil], they had to at some point. Age will always catch up with you at some point but the national team have a bright future. Spanish football coaches work very well with the youngsters and with the talent there is out there, so I'm not worried."
