The Brazilian was heavily linked with a move to Camp Nou in the summer, with the Catalan giants making a total of three bids, with one totalling a massive €130 million.
Liverpool managed to resist their advances and retain Coutinho, who has since scored four goals and provided three assists in nine appearances in all competitions for the Reds.
Ronaldinho, a Brazilian icon and a legend at Barca, has closely followed the 25-year-old's career, and believes he would be a shrewd addition to Ernesto Valverde's squad.
"I believe the way he plays will perfectly suit Barcelona and would be delighted to see a player of such quality wear the shirt.
"I like the way Coutinho plays and the type of football he brings. Those types of qualities will hopefully help Brazil win the next World Cup."
