Sergio Aguero would be a "coup" for Barcelona, according to Rivaldo, who says the Manchester City star's arrival at Camp Nou might convince Lionel Messi to stay put.
Aguero will bring the curtain down on his illustrious 10-year career at Etihad Stadium when his contract expires in June.
Barca are among the clubs being tipped to sign the Argentine on a free transfer when he leaves City, and Rivaldo thinks he could help Messi make a final decision on his own future if he links up with his compatriot in Catalonia.
