Hazard joined Real Madrid in the summer of 2019 after spending seven years in the Premier League with Chelsea, and things have not gone as planned for the Belgian, who is yet to hit his recognized standards in the Spanish capital.
The 30-year-old’s time with Los Blancos has been marred with constant injuries and inconsistency in his performances.
Bico believes Hazard delayed in moving to La Liga and the playing style of the Catalan giants would have suited the Belgium international.
"It was a mistake to go to Real [Madrid] at that time, it was a choice from the heart but for no clear reason," Bico told Derniere Heure.
"He should have left a year earlier. Going [to Real Madrid] after [Ronaldo] is like climbing the Himalayas with bare hands.
"I would have discouraged him by telling him to go to Madrid the year before."
"People do not realise and forget the size of this club, who have a style that demands a lot of physicality in terms of pace and intensity," he added.
"Talents like James [Rodriguez] have not been able to adapt. At this point, Eden is not a Real Madrid player, rather a Barcelona player.
"Barcelona is where he should have gone, where the ball runs faster than the players.
"At Barcelona he would have had more freedom on the pitch, he would have had the ball constantly at his feet. There, he would have become the best player in the world."
Hazard has played just 39 games for Real Madrid in all competitions and has scored only four goals in the process.
