Barcelona star Lionel Messi is the best player of all-time while Ronaldinho belongs among the greats, according to Xavi.
Messi is a record six-time Ballon d'Or winner and is considered among the modern-day greats, alongside Cristiano Ronaldo.
His former team-mate, Xavi, has no doubt the Argentina international is the greatest player ever.
"Ronaldinho is at the level of the best. Ronaldinho is at the level of the best, perhaps what he lacked was constancy," the Al-Sadd coach told Globo Esporte.
"Perhaps he lacked constancy in being at his peak. For me, only Messi is above Ronaldinho because of the constancy of the last few years."
Xavi added: "Messi is the best in history, but Ronaldinho is with the best. The rest follow.
"He [Ronaldinho] is with the best – with Ronaldo 'Fenomeno', with Cristiano Ronaldo, Messi, that group."
Messi had scored 24 goals in 31 games this season before the campaign was suspended due to the coronavirus pandemic.
