Ronaldinho and Sergio Aguero led a host of former and current team-mates who hailed Lionel Messi following his 500th Barcelona goal.
The 29-year-old star reached the landmark Sunday with two crucial goals against Real Madrid in a 3-2 Clasico win.

Messi's magic ensured Barcelona stayed alive in the title race, as they drew level with their arch-rivals having played one more game in La Liga.
And in an emotive video, Ronaldinho jokingly took the credit for the star's first Barca strike as he paid his respects.
"Leo, my brother, I am sending you a message to congratulate you on your 500 goals," the exuberant Brazilian said.
"I gave your the first of those 500 so I'm very happy, congratulations and all my love."
Aguero, who has been an international team-mate of Messi's since Argentina's Under-20 World Cup win back in 2005, also congratulated his close friend on the milestone.
