The brother and agent of Ronaldinho says the AC Milan midfielder would welcome a return to Barcelona.
Roberto de Assis said: "Barcelona will always be a special city to us. We would be happy to return. We love, respect and have love for the city and the club.
"Milan started well but then he suffered an injury that removed him from the team. It is a new stage in his life, long-term results will arrive in their own time."
