"It would be amazing to see a Barcelona side with Neymar and Messi," Ramalho told La Xarxa radio.
"Neymar is destined for Europe after the World Cup. He must choose the club he goes to wisely.
"The best option for me is Barca. Messi is close to becoming the greatest of all time, but he is yet to win the World Cup. Only then will he be at the level of Pele and Maradona."
